How to return all capital letters from a string in Python?

Question

Curious to see if there's a way to return all capital letters from a string in Python, not using is.upper, maybe using other conditionals?

Why not using `isupper`? Otherwise `return [i for i in s if i in string.ascii_uppercase`] would work — Cory Kramer, Oct 22 '17 at 14:35
Or if you want to impress her: `re.sub('[^A-Z]', '', your_string)` — Maroun, Oct 22 '17 at 14:36
@cᴏʟᴅsᴘᴇᴇᴅ `isupper` is not a function applied to a astring, but a method. That filter statement won't work. — user2390182, Oct 22 '17 at 14:41

One solution would be:

[char for char in _string if char.isupper()]

Without using anything other than list comprehension (that too can be replaced by normal for loop)

>>> [s for s in string if 'A'<=s<='Z']
=> ['A', 'D', 'F', 'G']

#driver values :

IN : string = 'AbcDeFGh2i'
