How to compare the first line from multiple files

Greetings,

 I'm new on the forum and relatively new to Python. I have been tasked
at work with checking some files for consistency.

 What I need to do is verify that the first lines of a group of text
files are identical.
 The files are all in the same directory.
 I know what the first line should be (or I can take the first line
from the first file as the reference.)

How would I go about doing this.

Thanks in advance.

Regards,
