经由指挥线的弹 Python
原标题:Python argparse passing list or dictionary via command line

我已经看到过有关通过独裁者的问题,并用一个富有活力的图书馆把沙德列入名单的问题。 这些例子都显示我的沙尔法。 但没有人告诉我他们喜欢指挥线。 在什么地方,我需要插手、方括号和引语?

因此,如果我想要的是参数——米——起诉和——米——列入我如何按照指挥线的要求具体说明这些参数?

这里是我想要完成的工作的实质:

Python foo.py --my_dict="{ Name :  Zara ,  Class :  First }" --my_list="[ a ,  b ,  c ]"
问题回答

您可使用ast.literal_eval,安全地将用户-投射中扼杀剂转换成Zardicts和清单:

import argparse
import ast
parser = argparse.ArgumentParser()
parser.add_argument( --my_dict , type=ast.literal_eval)
parser.add_argument( --my_list , type=ast.literal_eval)
args = parser.parse_args()
print(args)

驾驶

% python script.py --my_dict="{ Name :  Zara ,  Class :  First }" --my_list="[ a ,  b ,  c ]"

产量

Namespace(my_dict={ Name :  Zara ,  Class :  First }, my_list=[ a ,  b ,  c ])

你们将如何为定案清单这样做?
