如何在Python中对一组字符正确使用“Replace”方法

你的用法 replace 是错误的,因为您正在搜索字符串文本%d。这不是正则表达式。

您可以这样修复代码:

import re

words = ['Duration12:14254', 'Noun', 'Adjective7:888']
result = [re.sub(r'[0-9]+', r'[\g<0>]', w) for w in words]
repResult = [re.sub(r':\[(\d+)\]', r':\1', w) for w in result]
print(repResult)

你得到:

['Duration[12]:1', 'Noun', 'Adjective[7]:8']

与 ['Duration12:14254', 'Noun', 'Adjective7:888'] ,您将得到:

['Duration[12]:14254', 'Noun', 'Adjective[7]:888']

可以使用单个RegEx简化此代码:

import re

words = ['Duration12:14254', 'Noun', 'Adjective7:888']
result = [re.sub(r'(\d+):(\d+)', r'[\1]:\2', w) for w in words]
