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.
