Python regex doesn't detect square brackets
I have a script where I want to remove all special characters except spaces from a given content and I am working with Python and I have used this regex
re.sub(r"[^a-zA-z0-9 ]+","",content)
Itt removed all special characters, but didn't remove square brackets [ ]
and I just don't know why this is happening
after that i just use this regex
content = re.sub(r"[^a-zA-z0-9 ]+|\[|\]","",content)
It works flawlessly in IDLE IDE
and removes all special characters, but when I want to replace large files like the Wikipedia page then its now not remove the closing square brackets ]
I just don't understand why Python
this strange behavior does and

You have a lowercase z
where it should be upppercase. Change:
re.sub(r"[^a-zA-z0-9 ]+","",content)
in
re.sub(r"[^a-zA-z0-9 ]+","",content)
For recording range 'A-z'
extended to characters A...Z
, [
, \
, ]
, ^
, _
, ``
, A...Z
; why is your regex stripping everything but those characters.
