Regular expression to match words which does not start with particular charector in python using negative lookahead assertion [duplicate]

This question already has an answer here:

In the string

s = 'Makeupby Antonia #makeup #makeupartist #makeupdolls #abhcosmetics'


I want to match only word which does not start with #. Means I want to select only Makeupby and Antonia
I tried using negative lookahead assertion

#

Makeupby

Antonia

re.findall(r'b(?![#])[a-zA-Z]+',s)

['Makeupby',
'Antonia',
'makeup',
'makeupartist',
'makeupdolls',
'abhcosmetics']


But this is matching with all words. Where I am wrong?

(?!) is syntax for a negative lookahead. You want a negative lookbehind.

(?!)

try b(?<!#)[a-zA-Z]+

b(?<!#)[a-zA-Z]+
