Comparison of 2 text files in Python for a particular pattern

I want to compare a text file having some filenames with another text file that has the list of files but with extentions:-

For example:- TextFile 1 has files like "filename1","filename2" etc.

The file with which I want to compare may have the list of same files but with some extentions:-

eg:-"filename1-abc.ext","filename2-xyz.ext" etc.

Now I want to write a code in python that will compare the 1st text file with the second one and tell me whether they exist in the second textfile by ignoring the extentions.

Kindly help.
