Python -如何提取两个标记之间的子字符串？

使用正则表达式- 文档以供进一步参考

import retext = 'gfgfdAAA1234ZZZuijjk'm = re.search('AAA(.+?)ZZZ', text)if m:    found = m.group(1)# found: 1234

要么：

import retext = 'gfgfdAAA1234ZZZuijjk'try:    found = re.search('AAA(.+?)ZZZ', text).group(1)except AttributeError:    # AAA, ZZZ not found in the original string    found = '' # apply your error handling# found: 1234
