python - 在 Regex Python 中查找全部大写的行

Question

我正在尝试使用正则表达式查找所有大写的行，到目前为止我已经试过了:

re.findall(r'\b\n|[A-Z]+\b', kaizoku)

目前我的数据库如下:

TRAFALGAR LAW
You shall not be the pirate king.
MONKEY D LUFFY
Now!
DOFLAMINGO'S UNDERLINGS:
Noooooo!

我要它回来

TRAFALGAR LAW
MONKEY D LUFFY
DOFLAMINGO'S UNDERLINGS:

但它返回的是其他东西。(即:

TRAFALGAR
LAW
Y
MONKEY
D
LUFFY
N
DOFLAMINGO'
S
UNDERLINGS:
N

编辑到目前为止，我真的认为最适合的答案是@Jan 的答案

rx = re.compile(r"^([A-Z ':]+$)\b", re.M)
rx.findall(string)

EDIT2 找出问题所在，谢谢!

Answer 1

简介

不需要正则表达式，python有方法isupper()

Return true if all cased characters^[4] in the string are uppercase and there is at least one cased character, false otherwise.

_{[4] Cased characters are those with general category property being one of “Lu” (Letter, uppercase), “Ll” (Letter, lowercase), or “Lt” (Letter, titlecase).}

代码

See code in use here

a = [
    "TRAFALGAR LAW",
    "You shall not be the pirate king.",
    "MONKEY D LUFFY",
    "Now!",
    "DOFLAMINGO'S UNDERLINGS:",
    "Noooooo!",
]

for s in a:
    print s.isupper()

结果

True
False
True
False
True
False
