i am looking to find some words in a string of code i've already done for my class. i want to find if the abstracts of the literature i found includes the words "gene" or "genetic". so far i have
match = re.search(r"(gene|tic)"
which gives me 44 results; however, this expression is pulling anything that has the words gene or genetic in them (like general or biotic). how can i change this to only pull either gene or genetic, and nothing else? this must be a regular expression.
The following regex should match only on the exact 3 words "gene", "genes" and "genetic"
re.search(r"(\bgene(tic|s)?\b)")
\b
matches word boundaries (the beginning or end of a word) and (tic|s)?
optionally matches the string "tic" or "s".
Try r"gene(?:tic)?"
the tic is optional at the end.
