How to use a variable inside a regular expression?

Question

I\'d like to use a variable inside a regex, how can I do this in Python?

TEXTO = sys.argv[1]

if re.search(r\"\\b(?=\\         


        

Answer 1

if re.search(r"\b(?<=\w)%s\b(?!\w)" % TEXTO, subject, re.IGNORECASE):

This will insert what is in TEXTO into the regex as a string.
