使用re模块进行过滤

Question

我的清单如下：

['\'STATE\\\': \\\'("DEVELOPMENT COMPLETE", "DEVELOPMENT IN PROGRESS", "WIP QA")\\\'}, \']']

现在我想使用re模块从上述列表中筛选下面的部分

("DEVELOPMENT COMPLETE", "DEVELOPMENT IN PROGRESS", "WIP QA")

有人能帮我使用re模块吗

Answer 1

用途：

>>> l = ['\'STATE\\\': \\\'("DEVELOPMENT COMPLETE", "DEVELOPMENT IN PROGRESS", "WIP QA")\\\'}, \']'] 
>>> re.search(r'(\([^\)]*\))' , l[0]).group(1)
'("DEVELOPMENT COMPLETE", "DEVELOPMENT IN PROGRESS", "WIP QA")'

如果你想要你的结果是tuple，你可以使用ast

>>> import ast
>>> ast.literal_eval(re.search(r'(\([^\)]*\))', l[0]).group(1))
('DEVELOPMENT COMPLETE', 'DEVELOPMENT IN PROGRESS', 'WIP QA')

以防万一，如果您的列表包含多个元素，那么您可能需要迭代它，然后使用上面的re
