exit(0) means a clean exit without any errors / problems
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 ... | 4 | 211 | 0 | What's the difference between exit(0) and exit(1) in Python?

is no guarantee.
