Regular Expression Word Boarder

Question

I got a word 'myword' and i want to find all those words in a file, that contain 'myword' but not those who contain it at the beginning. Can you guys tell me how to do it by regular expressions in Python? I bet that i must use Word Boarder expression somehow.

Answer 1

\\b stands for word boundary, and \\B stands for "Not word boundary"

Following regular expression should work:

import re
matches = re.findall(r"\Bmyword", file_contents)
