main thread can't get the error

[swamper123]

Catching Exceptions, caused by Threads, in Python is a pain (since ever). You can't pass them to the main thread.
You have to integrate signals or deal with the Exceptions in the Threads themselve or at least join the thread anywhere.

Sure, thank you.Global variable as a integrate signals is good idea.

I thought more about signal.
Global variables can be a dangerous field. I hope you know, what you are doing.
