How to implement multithreading in the program?

Question

Python

When compiling a multi-threaded program on Windows, I ran into a problem that if __name__ == '__main__': does not work and when threads start, they start restarting themselves, how to fix it?
It seems that I read that there is such a problem with Windows, but I don’t remember where.
The problem is the current in the running program, if you run it from the command line, then everything works as it should.

Answer 1

If the file with if __name__ == "__main__":is started from some other file, then the if will not work.
Accordingly, if you need to use the file in a program with multithreading, you need to remove this if .

Answer 2

remove the if if you are using a program with multithreading. And that won't work
