Line-by-line debugging of Python code. And is it possible in Sublime Text?

Question

Python

I am newbie. I'm learning Python.
I'm currently using Sublime Text, having set up a Build System for Python.
That is, the code is executed in the console.
Sometimes there are situations when the code loops and you have to "kill" a process through the taskbar, which is endlessly running. Or I just can’t understand where I made a mistake and I want to see the line-by-line execution of the code with intermediate results.
An example of line-by-line validation is in the interactive tutorial I'm going through. But it does not work very correctly, and I would like to be able to do the same in Sublime Text.
Question:
Is this possible in Sublime Text? Or should I use something like PyCharm?
It seems to me that having dealt with the line-by-line check of the results, the training will go faster.

Answer 1

Maybe, maybe start with this ?

If you figured out how to install plugins, install SublimeREPL, and then:
Tools -> SublimeREPL -> Python -> Python - PDB
