搜尋過程, 以"python replace different string simultaneously" 作為關鍵字, 參考 https://stackoverflow.com/questions/6116978/how-to-replace-multiple-substrings-of-a-string/6117042 中所提供的方法, 可以同時將 config/content.htm 中的 h 各往後推送一階.

import re

rep = {"h1": "h2", "h2": "h3", "h3": "h4"} # define desired replacements here

# use these three lines to do the replacement
rep = dict((re.escape(k), v) for k, v in rep.items())
pattern = re.compile("|".join(rep.keys()))

#text = pattern.sub(lambda m: rep[re.escape(m.group(0))], text)

result = pattern.sub(lambda m: rep[re.escape(m.group(0))], "<h1>test1</h1>test1<h2>test2</h2>test2<h3>test3</h3>test3")
print(result)
