                 SCRIPT MODE (EDITOR’S WINDOW)
                 Python Shell executes commands immediately and doesn't save them for later use. For multi-
                 line code and to save your work for future use, you should use Python script mode. This allows
                 you to write larger programs and run the same code multiple times. Save your code in a file, for
                 example, 'filename.py', and run it to see all the output after execution. To open Python Editor’s
                 Window: click on the File menu    click on the New File option.









                 The output is displayed in the Python Shell window.




                           INPUT AND OUTPUT

                 Python  provides  two  commonly  used  functions  input()  and  print()  for input  and  output
                 respectively.

                 THE input() FUNCTION
                 We use the input() function to take the user’s input while a program is being executed. (This
                 function also evaluates the expression whether the user has entered a string, number or list right
                 after receiving input.) The general syntax of the input() function is as follows:

                 Variable_name = input(<message to be displayed>)
                 Example:
                 >>> name = input("Enter your name: ")
                      Enter your name: Trackpad

                 By default, Python considers the input as string even if you entered a number as input. You cannot
                 perform calculations on string. To perform calculations, you need to convert the string into integer
                 or floating-point value.
