Facing issue in python regex newline match

[snippsat]

Added r.

import re

input_string =\
""".Myc PGGGGG_UIII_Q9999_AB A0 B11 B22 D1 D2 D3
+ 4I 3B"""

pattern = r'\.(myc|Myc)\s+([a-zA-Z0-9\_\-]+)\s+(.*)\n(.*)'
matches = re.findall(pattern, input_string)[0]
print(matches)

Output:
('Myc', 'PGGGGG_UIII_Q9999_AB', 'A0 B11 B22 D1 D2 D3', '+ 4I 3B')
>>> matches[0]
'Myc'
>>> matches[-1]
'+ 4I 3B'
