Why do I have an error?
print(re.findall(r''' \b+@[-\w\d.]* #First a word boundary, an @, and then any number of characters [^gov\t]+ #ignor 1+instances of the letters 'g', 'o' or 'v' and a tab. \b #Match another word boundary ''', data, re.VERBOSE|re.I))

+ means "one or more". The word boundary character
\b is a "zero-length" character as it matches a position but no specific character therefore you can not have "one or more" boundary characters. The specific error is "
nothing to repeat"
\b+" to "
\b" should fix your error.
