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 To close IDLE window:
future use, you should use Python script mode. This allows you to Short key
write larger programs and run the same code multiple times. Save Ctrl + D
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

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.
