consider-using-sys-exit / R1722

Message emitted:

Consider using 'sys.exit' instead

Description:

Contrary to 'exit()' or 'quit()', 'sys.exit' does not rely on the site module being available (as the 'sys' module is always available).

Problematic code:

if __name__ == "__main__":
    user = input("Enter user name: ")
    print(f"Hello, {user}")
    exit(0)  # [consider-using-sys-exit]

Correct code:

import sys

if __name__ == "__main__":
    user = input("Enter user name: ")
    print(f"Hello, {user}")
    sys.exit(0)
