Introduction:

1. We can be able to generate the Random integer values by using the randint() function. 

2. When we are going to use the function randint() then it is used to takes two arguments such as start and end.

3. Here the start and the end are used to denote the range for the integer to be generated values. 

4. When we are concern about the Random integers, then they are used to be get generated within the boundary values. Here the boundary values are the start and end of range values.

5. More specifically they are the interval [start, end].

Here, I am going to discuss about How to generate the Random Integer in Python. Here we are also going to discuss that how they are used to support the inbuilt functions which is being provided by the Python library.

What is Random Number Generator in Python:

1. A Random Number Generator in Python is a function which is used to generate the random number whenever it is get called.

2. It is a built-in function in Python.

3. It is a function which is present in the Python Random module. 

4. So, whenever we need to generate the random number we need to call this module and invoke the Generate method.

5. Along with this method this module also consists of other random number generator functions methods such as seed(), randrange(), randint(), choice(), shuffle(), sample() and uniform().

6. These methods are also called as supporting methods for Random number generation.

7. The seed() method is basically used to produce the values which are deterministic in nature.

8. A deterministic value are used to have the same sequence of values.

9. The randrange() method is basically used when we need to return random values between the specified limit and interval.

10. The randint() is basically used when we are going to returns a random integer as per the given limit.

11. The choice() method is basically get used when we need to return a random number form a given sequence of numbers.

12. The suffle() method is basically used when we need a suffle a value within a given sequence of numbers.

13. The sample() method is basically get used when we need to return a randomly selected values.

The uniform() method is basically get used when we need to returns the floating-point values form a given range of values.

Generating integers:

1. As we have already discussed that if we are going to generate the Random integers values then it can be get generated using functions such as randrange() and randint() methods. 

2. The randrange() method is basically used when we need to return random values between the specified limit and interval.

3. Similarly, The randint() is basically used when we are going to returns a random integer as per the given limit.

Let us consider the example as discussed below which will let you know how to use these methods.

randrange():

1. As we know that the randrange() function is basically used when we need to return random values between the specified limit and interval. 

2. It is basically used to allow the user to generate values by stepping over the interval count.

Syntax:

randrange()

Let us consider the following example which shows the use of randrange().

import random

for x in range(5):

    print(random.randrange(2,60,2))

randint():

1. When we are going to use the randint() method then it is basically used to generates integers between a given limit. 

2. Here It will takes two parameters as an input which are used to specifies the limit values. 

3. Here lower limit is get specified by first parameter whereas the second specifies the upper limit.

Syntax: 

randint(a,b) 

here a is the lower limit and b is the upper limit.

Example:

import random

random.randint(1,5)

Similarly, if we need to generate the series of sequence then we may take the approach of loop here. But it should be get noted that we need to put the function as a body of the loop.

For Example:

import random

for x in range(2):

    print(random.randint(2,11))

Generating floating-point numbers:

1. Like similar to above if we are going to generate the floating point number then we can use the random() and uniform() method.

2. When we are going to use the random() method then it produces floating-point values between 0.0 to 1.0.

3. Like other method it never used to takes any parameters. 

4. Here the upper limit is excluded. So, the maximum value it can range up to 9.999.

5. When we are going to use the uniform() method then it is basically get used when we need to returns the floating-point values form a given range of values

Let us consider the following example which will let you know about the use of random() and uniform().

Example:

Use of random():

import random

for x in range(5):

    print(random.random())

Use of uniform():

for x in range(5):

    print(random.uniform(6))

Generating values from a given sequence:

1. When we are going to generate the values form a sequence then we use the choice().

2. The choice() method is basically get used when we need to return a random number form a given sequence of numbers.

Let us consider the following example:

for x in range(3):

    print(random.choice([1,2,3,4,5,6,7,8,9]))

Like similar to choice () some times we may also use the sample(). The use of sample() is almost similar as that of choice().

Let us consider the following example which will let you know how to use the sample().

x=random.sample([1,2,3,4,5,6,7,8,9],4)

print(x)

Other functions:

As we have already discussed above earlier that the other functions are also present which are used to generate the random number. Let us discuss one by one here.

shuffle():

1. The suffle() method is basically used when we need a suffle a value within a given sequence of numbers

Example:

x=[1,2,3,4,5,6,7,8,9]

random.shuffle(x)

print(x)

seed():

1. This method is also called as supporting methods for Random number generation.

2. The seed() method is basically used to produce the values which are deterministic in nature.

3. A deterministic value is used to have the same sequence of values.

Let us consider the following example as below:

random.seed(2)

print(random.random(),random.random(),random.random(),end='nn')

It should be get noted that This function is very useful when we need to pass the same random numbers to various test cases.

Introduction:

1. The PIP is basically defined as it is a package manager for Python packages, or modules.

2. When we are using the Python 3.4 Version or later then it is present by default.

3. A Package is a collection of precompiled class which we usually need for writing a program or developing a project work.

4. A package is also a collection of Library.

5. In most of the cases if we need to check whether PIP is present in our Python Library or not we need to use the following command as

6. C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip --version   

Here, I am going to discuss about the PIP in Python regarding its use and implementation. Here we are also going to discuss that how we can install the PIP if we are using the earlier version of Python.

What is PIP:

1. As we have already discussed earlier that the PIP is a Package Manager for Python.

2. In most of the cases if we need to check whether PIP is present in our Python Library or not we need to use the following command as

C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip --version   

3. When we are going to implement the concept in programming then we may need the PIP as a environment.

How to Install PIP In Python:

As we have already discussed that if we are going to have the Python 3.4 version onwards with us then it is by default present in the system. But if we are using the Python 2 then we need to install the PIP manually. To do so we need to proceed as follows.

1. As stated earlier we first need to Check if PIP is Installed in our system or not. To do so we need to navigate our command line to the location of Python's script directory.

2. For this we need to type the following command in the console as: C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip –version

3. If you do not have PIP get installed in your system then you need to Install PIP by redirecting to the following link: https://pypi.org/project/pip/

4. Downloading a PIP package is very easy just we need to Open the command line interface and download the package you want to install in your system.

     5.Navigate your command line to the location of Python's script directory,            and type the following:                    C:\Users\YourName\AppData\Local\Programs\Python\Python36-32\Scripts>pip install camelcase

     6.It is the first package that you have installed in your system and it is ready to use.

7. Now you need to Import the "camelcase" package into your project. The code for doing this is as mentioned below.

import camelcase

c = camelcase.CamelCase()

txt = "hello world"

print(c.hump(txt))

Similarly, if you need to install the PIP separately then you need to follow the following steps mentioned as below.

1. Download the package form internet get-pip.py

2. Open Command prompt and Run the following command such as C:\ Users\YourName\python get-pip.py

Similarly, if you need to upgrade the PIP version in your system, you need to type the following command as C:\ Users\YourName\python -m pip install –upgrade pip

Now after this you are ready with your updated PIP in your system and it is ready to use.

Installing A Library:

For the installation of library in PIP, If you’re using Windows, then open the Windows Command Prompt, and then typing this command:

pip install package name

For example, if we need to install the scikit-learn package, then we can type the command as 

pip install scikit-learn

It will install the package to your system. The screen shot you will receive by the system as

In the similar manner you can be able to install any package as per your wish. But it should be get noted that if you need to install a specific version of library package then you need to mention it. 

For example, if I need to install the version 0.19.2 of scikit-learn then I need to mention it as

pip install scikit-learn==0.19.2

Introduction:

1. Presently the Python is considered as a more powerful language because it has provided a great tool and enriched library for data crunching and preparation. 

2. The use of super () in Python is mostly used to make the program more dynamic.

3.  It is the concept which is mostly used in Inheritance programming when we need to refer to multiple classes or parent classes without having to name them first.

Here, I am going to discuss about the Super () in Python regarding its use and implementation. Here we are also going to discuss the example and then we will explain the working approach of super () in details.

Introduction to Super Function:

1. As we have already discussed earlier that the super() in Python is mostly used to make the program more dynamic.

2.  When we are going to implement the concept of single inheritance programming then if we need to refer to multiple classes or parent classes without having to name them first then super() is get used.

3. Sometimes when we need to return a proxy object while using the delegates method calls to a parent or sister class of type then Super () is used. 

4. When we are going to implement the concept of overriding in a class for accessing the inherited methods then super () is going to be used.

Let us consider the following example which will let you know how to write a super() in Python. Mostly in Python 3 when we need to write a program using super() then it has to go through the following manner.

Example:

class MyParentClass():
def __init__(self):
pass 
class SubClass(MyParentClass):
def __init__(self):
super()

Here we are going to discuss the concept in more detailed way.

Making use of Super in your Programming:

As we have already discussed above that it is a technique in which we need to return a proxy object while using the delegates method calls to a parent or sister class. Also when we are going to implement the concept of single inheritance programming then if we need to refer to multiple classes or parent classes without having to name them first.

It should be noted that If you are using Python version 3.0 and above, the method for using super function is as follows.

super().methoName(args)

If you are using an earlier build of Python, the syntax for super function will be,

super(subClass, instance).method(args)

Let us consider the following example which will let you know how the use of super()  will take place in a program.

Example:

When we are going to use the super() in inline approach then the technique for implementation will be as follows.

class MyParentClass(object):
def __init__(self):
pass
 
class SubClass(MyParentClass):
def __init__(self):
MyParentClass.__init__(self)

But on the other hand if we are going to use earlier version of Python like Python 2 then the implementation will be like as below.

class SubClass(MyParentClass):
def __init__(self):
super(SubClass, self).__init__()

Let us consider the following program which will let you know the use of super(). Here in the following program the we are having a class called Square and an another class called Cube which is going to inherits the class Square. The code is as showed below.

Program:

class Square: 
     def __init__(self, side): 
         self.side = side 
  
     def area(self): 
         return self.side * self.side 
  
class Cube(Square): 
      def area(self): 
         face_area = self.side * self.side 
         return face_area * 6
  
     def volume(self): 
         face_area = self.side * self.side 
         return face_area * self.side 

Note:

Here in the above program it should be get noted that the  Cube class does not have an __init__() method. So the __init__() of Square class will be used for initialization of Cube instances. It is the basic property of inheritance mechanism which we are going to implement here.

As we have already discussed above that super() is basically used to returns a proxy object of the parent class so, when we are going to call the method  area() of Square class using super() as, super().area(). Then it is usually going to be accomplished as a modified definition of the class Cube.

class Cube(Square): 
     def area(self): 
         return super().area() * 6
  
     def volume(self): 
         return super().area() * self.side() 

Uses of Super Function in Python:

1. The super function in Python is proved to be extremely useful for forwarding compatibility. 

2. It enables the concept of code reusability what Inheritance concept is used to provide.

3. If we are going to use correctly then it diminishes the requirement of declaring the characteristics of all the classes.

4. If we are going to use the super() then it must be present within your Python library.

5. Because, during the execution, both the callee as well as caller functions must have the same signature as well as address otherwise it will give you the error.

6. If we need to use a super function, then we need to call it by using the super() keyword.

7. If we are going to use a zero argument form of super() then it can be done when we can only be used inside a class definition.

8. As it is used to support the concept of auto-filled by the compiler so if we use super() inside a class, say X, super() will be converted into super(X, self) by the compiler.
