Non-Capturing Group (Image URL) in PY

Use non-capturing groups `(?:...)` to alternate without polluting the captured-groups list.

Pattern

regexPY
(?:https?:\/\/)\S+\.(?:jpg|jpeg|png|gif|webp|svg)   (flags: gi)

Python (re) code

pyPython
import re

pattern = re.compile(r"(?:https?:\/\/)\S+\.(?:jpg|jpeg|png|gif|webp|svg)", re.IGNORECASE)
input_text = "Logo at https://example.com/logo.png and https://cdn.io/img.svg"
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

(?:https?:\/\/) groups the protocol options without capturing them — useful when you only care about matching, not extracting. \S+ matches the non-whitespace URL body. \.(?:jpg|jpeg|png|gif|webp|svg) matches the dot and extension via another non-capturing group. The pattern has zero capture groups; switch to `(...)` if you need to extract pieces.
