Python regex match, but exclude if regex match
I'm trying to write a regex for re.search that can match a string as long as the word prod exists anywhere in the text (.*prod.*). however, it should fail the match if the string should have the word orange anywhere in it.
web-prod-green# should matchweb-prod-orange# should fail to matchweb-orange-green# should fail to matchorange-prod-green# should fail to match
How can i do this? Thanks.

We could use a negative lookahead to exclude the presence of orange:
^(?!.*\borange\b).*\bprod\b.*$
