How to stop exit python script when other python script exits ?

Question

I am new to python language. My problem is I have two python scripts : Automation script A and a main script B. Script A internally calls script B. Script B exits whenever an exception is caught using sys.exit(1) functionality. Now, whenever script B exits it result in exit of script A also. Is there any way to stop exiting script A and continue its rest of execution, even if script B exits.

Thanks in advance.

Exactly how are you calling scriptB? via import or some sort of syscall? — Torxed

You should encapsulate the code in a try except block. That will catch your exception, and continue executing script A.

Thanks for your reply. This would work if script B was throwing an exception. However script B is calling sys.exit(1) in my case which causes the program to exit completely.

Except SystemExit: should catch it

sys.exit() actually raises a SystemExit exception which is caught and handled by the Python interpreter. All you have to do is put the call into to "script B" into a try/except block that catches SystemExit before it bubbles all the way up. For example:

try:
    script_b.do_stuff()
except SystemExit as e:
    print('Script B exited with return code {0}'.format(e.code))
