Python Regex 只匹配每个单词大写的地方

Question

我想匹配所有单词都大写的字符串。

目前我尝试过这样的事情:

list = ["This sentence should Not Match", "This Should Only Match"]
match = []
for l in list:
   x = re.search("^[A-Z]*.", l)
   if x:
      match.append(l)

例如，我希望正则表达式只匹配类似:“This Is A Good Example Here”，但不应匹配:“Something like this Here”，“HERE Is an example that Should NOT Match”，“TiHiS SeNtEnEcE”或“这不应该匹配.Foo”

我正在遍历大量新闻文章并尝试匹配所有标题。这些标题通常每个单词都大写。

你可以不用正则表达式:

l = ["This sentence should Not Match", "This Should Only Match"]
[s for s in l if s.istitle()]

输出:

['This Should Only Match']
