Interactive Shell#
With the interactive shell you can easily run most of the examples in this tutorial. Later, you will also learn how to easily include code written to a file as a module.

You can start the interactive Python shell in
.Alternatively, you can search for the directly executable file

, for example in
C:\Users\VEIT\AppData\Local\Programs\Python\Python310-64
and
then double-click.
You can scroll through previous entries with the arrow keys Home, End, Page up and Page down and repeat with the Enter key.
Exiting the interactive shell#
To exit the interactive shell, simply use Ctrl-d on Linux and macOS or
Ctrl-z on Windows. Alternatively, you can type exit()
.
IDLE#
IDLE is the acronym for integrated development environment and combines an interactive interpreter with code editing and debugging tools. It is very easy to execute on the various platforms:
Enter the following into your terminal:
$ idle-python3.10
You can start IDLE in
You can scroll through the history of previous commands with the alt-p and alt-n keys.
