Extract All Regex Matches With Python

import re
def extractImages(filename):
imgReg = re.compile("../assets/(.*jpg|.*png)")
with open(filename, mode="rt", encoding="utf-8") as docFile:
doc = docFile.read()
images = re.findall(imgReg, doc)
return ["./assets/" + img for img in images]
# later used in e.g. [os.remove(img) for img in extractImages(filename)]
# above deletes all images located in ./assets/<filename>.jpg|png
  1. define regex and assign it within the regex compile object with reg = re.compile(<regex>). You of course need to define a capture group to be extracted I.e. with http://pavol.kutaj.com/assets/(.*jpg|.*png) — only the image filename and not http://pavol.kutaj.com/assets/ location is extracted
  2. open the file with with open(...) as alias: statement
  3. assign the content of the file with inputObj = alias.read()
  4. assign the list of matches with matches = re.findall(inputObj, reg)
