怎么样：
import argparseif __name__ == '__main__': parser = argparse.ArgumentParser(description = "Print a range.") parser.add_argument("start", type = int, help = "Specify start.", ) parser.add_argument("stop", type = int, help = "Specify stop.", ) parser.add_argument("step", type = int, help = "Specify step.", ) args=parser.parse_args() print(args)产生
% test.py -husage: test.py [-h] start stop stepPrint a range.positional arguments: start Specify start. stop Specify stop. step Specify step.optional arguments: -h, --help show this help message and exit
