Difference between exit(0) and exit(1) in Python - Stack Overflow

exit(1) means there was some issue / error / problem and that is why the program is exiting. This is not Python specific and is pretty common. A non-zero exit code is treated as an abnormal exit, and at times, the error code indicates what the problem was. A zero error code means a successful exit.

Exit codes in Python - Stack Overflow

In Unix/Linux, the standard is: exit 0 in the case everything was ok. Type a command, then echo $?: if you read 0, it returned without an error. The idea is to have standard tests. If the code xyz.py did not encounter any error, it SHOULD return 0!
