timeit.main()

timeit.main(args=None, _wrap_timer=None)

Main program, used when run as a script.

The optional ‘args’ argument specifies the command line to be parsed, defaulting to sys.argv[1:].

The return value is an exit code to be passed to sys.exit(); it may be None to indicate success.

When an exception happens during timing, a traceback is printed to stderr and the return value is 1. Exceptions at other times (including the template compilation) are not caught.

‘_wrap_timer’ is an internal interface used for unit testing. If it is not None, it must be a callable that accepts a timer function and returns another timer function (used for unit testing).
