列表中变量的Python搜索正则表达式 [英] Python search regex from variable inside a list

问题描述

我有:

data = [[u'text'],[u'element'],[u'text00']]
pattern = text
pattern2 = EL
pattern3 = 00 

使用正则表达式，我要搜索并返回:

Using regex I want to search and return:

text, text00 # for pattern
element      # for pattern2
text00       # for pattern3

推荐答案

import re
data = [[u'text'], [u'element'], [u'text00']]
patterns = [u'text', u'EL', u'00']
results = []
for pattern in patterns:
    results.append([x[0] for x in data if re.search(pattern, x[0], flags=re.I)])
print  results

或更简洁地说:

import re
data = [[u'text'], [u'element'], [u'text00']]
patterns = [u'text', u'EL', u'00']
results = [[x[0] for x in data if re.search(pattern, x[0], flags=re.I)] for pattern in patterns]
print  results
