How to catch an error thrown inside an imported module-CodePudding

I have a custom module with a function, and I am importing it to my main file. When there is an exception raised in the module, I want to catch it in the main file.

Is this possible? I'm having a hard time finding any examples of this online or in the exception documentation.

Example:

exceptionStuff.py

class My_Error(Exception):
    pass

def Fail_Func():
    raise Exception

main.py

from myModules.exceptionStuff import My_Error

try:
    My_Error()
except:
    print('caught')

The exception doesn't get caught here.

CodePudding user response：

If you reorganize exceptionStuff.py like this

class My_Error(Exception):
    pass

def Fail_Func():
    raise My_Error

And your main file like this

from exceptionStuff import My_Error, Fail_Func

try:
    Fail_Func()
except My_Error as e:
    print(e.__class__.__name__)
    print('caught')

You will successfully catch an exception of type My_Error.

Output:

My_Error
caught
