python括号内内容_在python中从括号内提取数据

很有趣。你真的在这件事上对我。。。在def parse(tokens):

""" take iterator of tokens, parse to dictionary or atom """

dictionary &＃61; {}

# iterate tokens...

for token in tokens:

if token &＃61;&＃61; ")" or next(tokens) &＃61;&＃61; ")":

# token is &＃39;)&＃39; -> end of dict; next is &＃39;)&＃39; -> &＃39;leaf&＃39;

break

# add sub-parse to dictionary

dictionary[token] &＃61; parse(tokens)

# return dict, if non-empty, else token

return dictionary or int(token)

安装和演示&＃xff1a;

^{pr2}$

或者&＃xff0c;也可以使用一系列字符串替换将该字符串转换为实际的Python字典字符串&＃xff0c;然后对其进行求值&＃xff0c;例如&＃xff1a;as_dict &＃61; eval("{&＃39;" &＃43; s.replace(")", "&＃39;}, ")

.replace("(", "&＃39;: {&＃39;")

.replace(", ", ", &＃39;")

.replace(", &＃39;&＃39;", "")[:-3] &＃43; "}")

这将把“leafs”包装在单个字符串集中&＃xff0c;例如&＃xff0c;{&＃39;8&＃39;}而不是{}&＃xff0c;但这应该很容易在后处理步骤中修复。在
