Unable to extract words which doesnt start with character c using regular expression

I have a string containing multiple lines with words, and I want to extract all words from the string except those that start with c.

I tried this

import re
inp='''bat
cat
mat
'''
pt=re.compile(r'[^c][a-z]+')
ma=pt.findall(inp)

I’m getting

['bat', '\ncat', '\nmat']

This works perfectly fine if I explicitly mention ‘at’

pt=re.compile(r'[^c]at')

Output for this is:

['bat', 'mat']

But it doesn’t work using pt=re.compile(r'[^c][a-z]+')

>Solution :

import re
inp='''bat
cat
map
'''
pt=re.compile(r'\b[^\nc][a-z]+')
ma=pt.findall(inp)
print(ma)

Output:

['bat', 'map']
