Why Can't I do Undo on my Python?

[honeylemonade]

Hi friends. I need your help! I am new at learning Python and still have little idea on how to work things out. One of it is, I can't do an Undo (Ctrl+Z like any normal Undo function would be) on the worksheet (is this the right name for it? Worksheet?). When I press the Ctrl+Z, it let out this instead ---> ^Z.


Any help would be appreciated. Thanks!

It is not a worksheet, it is a Python console or terminal. A terminal is not an editor, you just type new commands and it adds results after your commands.

Worksheets that execute Python code exist, they are the jupyter notebook but I wouldn't recommend that you start with this. It would give you more things to learn before you start anything concrete.

A simpler way to run Python is to start with an editor where you write the code, and you can UNDO, then you can run the code. A good editor for beginners of python is Thonny. I recommend that you start with this IDE (integrated development environment).

How are you running python? Do you run the python (or python3) command in a shell? Something like this in a Windows PowerShell?

Output:
PS C:\> python
Python 3.12.4 (tags/v3.12.4:8e8a4ba, Jun  6 2024, 19:30:16) [MSC v.1940 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> x = 3
>>> print(X^Z

Or are you using IDLE? IDLE is and IDE that comes as part of most Python distributions. It is not a good IDE, but it is better than typing directly into the Python interractive interpreter. If using IDLE, the IDLE shell understands that ctrl+z is an undo. IDLE also has a file editor.

Thonny is a better IDE than IDLE, but you have to install Thonny separately. Oops! Take that back. Looks like you can install Thonny and it will install Python 3.10 for you. Handy for new programmers.

I like Visual Studio Code. If you do programming with Visual Studio, you will find VSCode familiar.
