Enter Interactive Mode In Python

Question

I\'m running my Python program and have a point where it would be useful to jump in and see what\'s going on, and then step out again. Sort of like a temporary console mode.

Answer 1

code.interact() seems to work somehow:

>>> import code
>>> def foo():
...     a = 10
...     code.interact(local=locals())
...     return a
... 
>>> foo()
Python 3.6.5 (default, Apr  1 2018, 05:46:30) 
[GCC 7.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> a
10

Ctrl+Z returns to the "main" interpreter.

You can read the locals, but modifying them doesn't seem to work this way.
