SCRIPT MODE (EDITOR’S WINDOW)
Python Shell does not allow you to save our commands written on the command prompt, it gives
output immediately after pressing the Enter key. If you want to see all the output after completion
of the code, then you can use the Python script mode. It also allows you to type multi-line codes
that we save for further use.
To open Python Editor’s Window: click on the File menu click on the New File option.
The output is displayed in the next line in the same 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 executes. (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>)
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.
