这是一个使用 的示例argparse
,虽然它是一个延伸。我不会称之为完整的解决方案,而是一个好的开始。
class StoreInDict(argparse.Action):
def __call__(self, parser, namespace, values, option_string=None):
d = getattr(namespace, self.dest)
for opt in values:
k,v = opt.split("=", 1)
k = k.lstrip("-")
if k in d:
d[k].append(v)
else:
d[k] = [v]
setattr(namespace, self.dest, d)
# Prevent argparse from trying to distinguish between positional arguments
# and optional arguments. Yes, it's a hack.
p = argparse.ArgumentParser( prefix_chars=' ' )
# Put all arguments in a single list, and process them with the custom action above,
# which convertes each "--key=value" argument to a "(key,value)" tuple and then
# merges it into the given dictionary.
p.add_argument("options", nargs="*", action=StoreInDict, default=dict())
args = p.parse_args("--arg1=1 --arg2=foo --arg1=4".split())
print args.options
