RegEx works in regexr but not in Python re

Question

I have this regex: If you don't want these messages, please [a-zA-Z0-9öäüÖÄÜ<>\n\-=#;&?_ "/:.@]+settings<\/a>. It works on regexr but not when I am using the re library in Python:

data = "<my text (comes from a file)>"
search = "If you don't want these messages, please [a-zA-Z0-9öäüÖÄÜ<>\n\-=#;&?_ \"/:.@]+settings<\/a>" # this search string comes from a database, so it's not hardcoded into my script
print(re.search(search, data))

Is there something I don't see?

Maybe add r in front of string and copy paste from regexr? r"abcd\rawstring" — jupiterbjy

Besides what @jupiterbjy just pointed out, you should add some test data if you want any further help. :) — Cow

Just put the hitherto escaped hyphen in the first or last position of the class where it can't constitute a range: [a-z...\\- to [-a-z.... No need to escape it there. — oriberu

the pattern you are using on regexr contains \- but in your exemple shows \\- wich may give an incorrect regex. (and add the r in front of of the string as jupiterby said).
