Pattern

regexPY
^[A-Z]{3}$

Python (re) code

pyPython
import re

pattern = re.compile(r"^[A-Z]{3}$")
input_text = "USD"
for m in pattern.finditer(input_text):
    print(m.group(0))

Stdlib `re` module — no third-party dependency. Works on Python 3.6+.

How the pattern works

^[A-Z]{3}$ requires exactly three uppercase letters, anchored to the full string. This validates the FORMAT but not the existence of the code — pair with a lookup table to ensure it's a real ISO 4217 entry like USD, EUR, GBP.
