Facing issue in python regex newline match

[Shr]

Hi Everyone,

.Myc PGGGGG_UIII_Q9999_AB A0 B11 B22 D1 D2 D3
+ 4I 3B

I am trying to match the above two line using regex.

\.(myc|Myc)\s+([a-zA-Z0-9\_\-]+)\s+(.*)\n(.*) = Used this regex

It will print --> .Myc PGGGGG_UIII_Q9999_AB A0 B11 B22 D1 D2 D3

It is not going to newline(\n is NOT WORKING HERE). Please let me know how to go to newline in python regex.
Suggestions are appreciated.

Thank you!
