argparse的其他类
argparse.extra的Python项目详细描述
Python argparse.ArgumentParser子类
字典中argparser声明的快速示例：
import sys
from argparse.extra import DictArgumentParser
def run_testarg_processing(args, argv):
print 'testarg argument used'
ARGUMENTS = {'--use-something':{'dest':'use_something',
'action':'store_true',
'default':False},
'sub:testarg':{
#sub:testarg will create subparser 'testarg'
#depth of subargs is unlimited
'description':'Test arg subcommand',
'help':'Test help'
'func':run_testarg_processing,
'--use-sub-something':{'dest':'use_sub_something',
'action':'store_true',
'default':False},
}}
DEFAULTS_ONLY = ['func',]
def get_argparser(argsdict=ARGUMENTS):
#always create get_argparser function for your cli apps
#this will enable easy integration of subsequent applications
#with your argparser
return DictArgumentParser(argsdict, DEFAULTS_ONLY)
def main(args=sys.argv):
args, argv = get_argparser().parse_known_args(args[1:])
args.func(args, argv)
if __name__ == '__main__':
main()
