Python Crash Course ( 2nd edition)

[alok]

In using the book as you follow it , Chap. 1 ,2 ,etc. must you leave all that was entered in Sublime ,there. Or can it be cleared out as you learn a new code ? I am finding that it seems as you follow the book you must leave all this "working stuff" in sublime ,is that correct ?
Because it seems the next thing he teaches you to do may look back at something you did,in sublime, 3 or 4 pages back to work and if you don't leave all in sublime ( the enteries that work ) from previous things ,the next thing he is teaching you may not work.
Am I correct on this ?

No not at all,you can use whatever Editor you like.
The book is about Python that author use Sublime dos not matter at all.

Editor is a personal choice i like VS Code(the most popular bye a fair margin 39-million Python install),other good is one PyCharm Free Community.
So you have to try some editors to find one you like,Sublime is okay but not free as as eg VS Code is.
There are some easy editors to get started like Thonny , Spyder or eg PyScripter(i like this one if on Windows).
