Python：如何將兩字符串之間的內容替換掉？

I have this string(問題源碼)：

str = '''
      // DO NOT REPLACE ME //
      Anything might be here. Numbers letters, symbols, and other strings.
      // DO NOT REPLACE ME EITHER //
      '''

I want to replace whatever is between those two lines, but I do not want to replace those strings. How do I do this?

翻譯:我想替換兩字符串之間的內容，但不替換字符。如何實現？

解答:

解答源碼:

>>> s = '''
      // DO NOT REPLACE ME //
      Anything might be here. Numbers letters, symbols, and other strings.
      // DO NOT REPLACE ME EITHER //
      '''
>>> print(s)

      // DO NOT REPLACE ME //
      Anything might be here. Numbers letters, symbols, and other strings.
      // DO NOT REPLACE ME EITHER //
>>> import re
>>> start = '// DO NOT REPLACE ME //'
>>> end = '// DO NOT REPLACE ME EITHER //'
>>> replacement = 'stuff'
>>> match = re.match(r'(.+%s\s*).+?(\s*%s.+)' % (start, end), s, re.DOTALL)
>>> match.groups()
('\n      // DO NOT REPLACE ME //\n      ', '\n      // DO NOT REPLACE ME EITHER //\n      ')
>>> new = match.group(1) + replacement + match.group(2)
>>> print(new)

      // DO NOT REPLACE ME //
      stuff
      // DO NOT REPLACE ME EITHER //

解答原文:May cause problems if start or end contain special regex characters. In this case they don't.

翻譯:若是start 或 end 值中包含正值表達式的字符，在執行時可能會出問題.
