matlab - Can Python start the console while saving program variables?

Question

Similar to matlab, you can directly operate variables on the console after the program is completed, instead of starting an independent console program. I wonder if any Python IDE supports this behavior

Answer 1

Python’s own IDLE can do this. After you open a python file and run the module, you will find that you can control the variables in the file on the main console

I tried the Pycharm part myself, you go to Run/Edit Configurations...

Then add Interpreter options to the options of -i:

After running the script, the shell will keep and will not end there

In fact, you don’t need an IDE to do what you want

Suppose you have a python script test.py

a = 5
b = [1, 2, 3]

Use directly:

$ python -i test.py

Run test.pyAfter completion, Python will stop in the console and you can continue to interact

Or use:

$ python

After opening the python shell, use import to import test and execute it. Then you can control the variable:

>>> from test import *
>>> a
5
>>> b
[1, 2, 3]

This also has the same effect

Answer 2

Compared with the native python shell, iPython is easier to use. In addition, after integrating Matplotlib, you can draw matlab-like graphics.
