用于在某些两个字符串之间提取字符串的python正则表达式

Question

Let's assume I have a string

st = "'aaa': '1', 'bbb': '2.3', 'ccc': 'name'"

I want to extract from st the following

['1', '2.3', 'name']

How can I do this?

Thanks

Answer 1

You can first create dict by ast.literal_eval and then get values :

import ast

st = "'aaa': '1', 'bbb': '2.3', 'ccc': 'name'"

print (ast.literal_eval('{' + st + '}'))
{'aaa': '1', 'bbb': '2.3', 'ccc': 'name'}

#python 3 add list
print (list(ast.literal_eval('{' + st + '}').values()))
['1', '2.3', 'name']

#python 2
print ast.literal_eval('{' + st + '}').values()
['1', '2.3', 'name']

Answer 2

Doing it with ast module would be best, like jezrael did it. Here is another solution with regex:

import re

st = "'a': '1', 'b': '2.3', 'c': 'name', 'd': 229, 'e': '', 'f': '228', 'g': 12"
print re.findall(r'\'\S+?\':\s*\'?(.*?)\'?(?:,|$)', st)

Output:

['1', '2.3', 'name', '229', '', '228', '12']
