python 中是否可以有两个运行相同脚本的独立 shell？

Question

Essentially what I am looking for is a way to have two shells interacting with one script of the main program (Change variables and all that) and have the other shell see those changes. for example:

shell 1 gets asked with teh input what it would like to add to the list, and types in "apple"

shell 2 who is also running the same script would be able to enter view and see that shell 1 had entered apple to List[1].

List = ["Oranges"]
UserInput = input("enter another fruit or 'V' for view")
if UserInput == "V":
    print(List)
else:
    List.append(UserInput)

shell 1 gets asked with the input what it would like to add to the list, and types in "Apples" would see: "enter another fruit or 'V' for view">"Apples"

shell 2 who is also running the same script would be able to enter view and see that shell 1 had entered apple to List. would see: enter another fruit or 'V' for view">"V" [Oranges, Apples]

for my purposes the data would not have any collisions/errors with overwrite as two people would not be able to edit the same thing not sure if what i have said makes sense but i have tried previously using TKinter as a pop out shell but did not end up working.

I do not think you will need to go to the extreme with testing via separate shells. Understandably you want to make sure that when data is accessed that you don't fall into any locking problems. A quick google search will yield many examples of how to do MultiThreading, here's the first result I found: geeksforgeeks.org/multithreading-python-set-1 try this and learn a little about how this works.

Additionally, I would also recommend looking up testing realpython.com/python-testing and how to do this, because you should be able to test your precise situation without having to create two shell windows.
