                      print("hello", "friends", sep="$", end="!")                   hello$friends!

                      print("hello", "friends", end="!")                            hello friends!
                      print("hello")                                                hello
                      print()

                      print("friends")                                              friends
                      print("hello", end="%")                                       hello%friends

                      print("friends")
                      print("hello", "friends", "welcome", sep="#",                 hello#friends#welcome@
                      end="@")
                      print("I am in class", 9)                                     I am in class 9
                      a = 5

                      b = 10

                      print("Sum of two numbers is " + str(a + b))                  Sum of two numbers is 15
                      age = 14
                      print("I am ", age, " years old")                             I am 14 years old

                 NOTE:  sep and end are always the last two parameters after the objects in the print statements. However both
                       may have interchange positions.


                     print(10,20 ,sep="+",end="!")
                 OR
                     print(10,20, end="!",sep="+")
                 Output in both the cases will be same as both the statements are interpreted as same.


                         The input() Function


                 The input() function is used to take input from the user. When this statement executes then the flow of the
                 program stops and waits with the cursor blinking for the user to enter a value. The input given by the user is
                 always a string value in Python.

                 The syntax to use the input() function is:

                     input(prompt)
                 Where prompt is a string that works as a message for the user at the time of input. For example,
                    name = input("enter your name: ")

                   print(name)
                 When the preceding statement executes, it will ask to enter a name. When you enter the name and press the
                 Enter key, the entered name will be displayed on the screen:

                   enter your name: Chirag
                   Chirag
                 Let us take another example:

                   a = input("Enter first number: ") #line 1
                                                                                        Introduction to Python  389
