sys.exit() vs. break

What benefits does using sys.exit() have over using break in this particular problem? For example I did if attempt_count == 3: print("Too many attempts! Try again later!") break Would it have been better to use sys.exit()?

A "break" is only allowed in a loop, and it causes the loop to end but the rest of the program continues.

On the other hand, "sys.exit()" can be used anywhere and it causes the entire program to end.
