For doing a regex substitution, there are three things that you give it:
There are three things that the regex engine finds that are of interest to me:
re.sub, the final string is what's returned. But is it possible to access the other two things, the matched string and replacement string?
Here's an example:
orig = "This is the original string." matchpat = "(orig.*?l)" replacepat = "not the \\1" final = re.sub(matchpat, replacepat, orig) print(final) # This is the not the original string
The match string is
"original" and the replacement string is
"not the original". Is there a way to get them? I'm writing a script to to search and replace in many files, and I want it to print it what it's finding and replacing, without printing out the entire line.
