For example,

             # assigning a value to a variable

                  num1 = 10
                  num2 = 20
            # calculating the average

                  (num1 + num2) / 2

            Multiple Line Comments
            When we add up comments which occupy two or more lines then we begin the comment with either 3 times
            single quotes ''' or double quotes """, followed by text on multiple lines and end with single quotes ''' or double
            quotes """ to mark the end of the comment. For example,

              """This program calculates
                  the average of

                  two numbers stored in
                  two different variables"""

                  a = 10
                  b = 20

                  c = (a + b) / 2

                    The print() Function

            The print() function is used to print an output on the screen. It converts the expressions into a string before
            writing to the screen. Syntax to use the print( ) function is:

            print(object(s), sep = separator, end = end)
            Where,
               • object can be one or more separated by comma and it can be a variable, literal, expression. An object will be
              converted to string before printed.

               • sep is used as a separator if there are more than one objects.
               • end specifies what to print at the end. Default is newline '\n'.
            Following are some of the examples of the print( ) function:

                                          Commands                                         Output

                 print("hello")                                                hello

                 print("hello", "friends")                                     hello friends
                 print("hello" + "friends")                                    hellofriends

                 (This is concatenation of string using "+"
                 operator)
                 print("hello", "friends", sep="$")                            hello$friends
                 print("hello", "friends", sep="$", end="!")                   hello$friends!

                 print("hello", "friends", end="!")                            hello friends!
                                                                                   Introduction to Python  305
