Creator Guido van Rossum named the language 'Python', after the popular
                    BBC comedy series  "Monty  Python's  Flying  Circus”.  He wanted  to  select  a
                    name that was a little bit mysterious and unpredictable.





                 Input Statement in Python

                 In python, to take input from the user we use input() function. This input() function prompts the
                 user to enter data.

                 Syntax:
                   input([ prompt] )
                 This input() considers all user input as string. Whether the user enters a number or a string but the
                 input() treats them as strings only. So, in order to consider the input value as other than string, we
                 have to convert it into other datatype.
                 For example:

                   A=input("Enter your N ame")  Here the input entered is String
                                                    #
                   B=input("Enter your mark s")  # Here the input is again String, but we cannot do
                   calculations on String. So it is converted into other data types.
                 Thus, the changed statement will be:
                   B=int(input("Enter your Mark s") )  To enter integer data values.
                                                            #
                   C=float(input("Enter your Price of the item")) # To input decimal values.

                 Output Statement in Python

                 The print() outputs a complete line and then moves to the next line for subsequent output.
                 Syntax:

                   print(value[ ,… .sep= " ",end='\n'] )
                 For example:
                   a=10
                   print("value of a",a)
                 Example 1: Input and Output statements in Python

                 Program:                                                     Output:
                   # Python program to swap two variable
                                                                                enter first number  3
                   values
                                                                                enter second number 45
                   num1=int(input("enter first number"))
                                                                                Now the value of num1 45
                   num2=int(input("enter second number"))
                                                                                Now the value of num2 23
                   temp=num1
                   num1=num2
                   num2=temp
                   print("N ow the value of num1",num1)
                   print("N ow the value of num2",num2)
