Searching for a raw string (r'\n') within a raw string full of ('\n') resulting in an empty result set

import re
re.search(r'\n',  r'\n\n')

Is resulting in an empty result-set. Should this pull the raw string '\n'?

Thanks

A string `r'\n'` contains 2 chars, a backslash and `n`, while `r'\n'` regex matches a newline. – Wiktor Stribiżew Jul 20 '17 at 16:28
However, I converted both the pattern and string to raw strings. Shouldn't that mean the regex is trying to match two characters, which is within the string? – Moondra Jul 20 '17 at 16:32

`r'\n'` and `'\n'` regex patterns both match a newline. – Wiktor Stribiżew Jul 20 '17 at 16:33
I see - that's super confusing. Thanks for the clarification. – Moondra Jul 20 '17 at 16:36
The string contains a backslash and an n, but `re.search` doesn't mean "search for this string". "Search for this string" is just `str.find`. – user2357112 Jul 28 '17 at 20:54
