The standard convention for all C programs, including Python, is for exit(0) to indicate success, and exit(1) or any other non-zero value (in the range 1..255) to indicate failure. Any value outside the range 0..255 is treated modulo 256 (the exit status is stored in an 8-bit value). Sometimes, that will be treated as signed (so you might see -128, -127, etc) but more usually it is treated as unsigned.

This status is available to the code that invoked Python. This convention applies across platforms, though the meaning of non-zero exit status can vary on different platforms.
