RegEx Python: extract substring from string

I have several strings (some values may differ but format is ultimately the same):

"I Suck At Regex: 100.00 WHATIWANT Plz Help: Thank you: 200.00"
"I Suck At Regex: 200.00 WHATIWANT Plz Help: Thank you: 200.00"
"I Suck At Regex: 300.00 ALSOWANT Plz Help: Thank you: 300.00"

I would like to extract the substring ‘WHATIWANT’ from the full string

I tried using [A-Z] to only extract capitalized letters, however, as you can tell, my string has capitalized letters in other positions

>Solution :

How about this:

import re

strings = [
    "I Suck At Regex: 100.00 WHATIWANT Plz Help: Thank you: 200.00",
    "I Suck At Regex: 200.00 WHATIWANT Plz Help: Thank you: 200.00",
    "I Suck At Regex: 300.00 ALSOWANT Plz Help: Thank you: 300.00"
]
# match a sequence of letters in the range A-Z with a length of at least 2
p = re.compile(r'\b([A-Z]{2,})\b')

for string in strings:
    print(*p.findall(string))

Output:

WHATIWANT
WHATIWANT
ALSOWANT
