Help to understand output

[Pippi]

Hi, I have loaded a lot of files under one variable. The output looks like this:

[Seq('KATIPSESP', ProteinAlphabet()), Seq('PSESPFAAA', ProteinAlphabet())]
[Seq('ASRLLLNNG', ProteinAlphabet()), Seq('SRLLLNNGA']

I need to compare the different list, but I am unsure how to do that because I am unsure of the output. Everything I do, is done to each list. Eg:

print(protein[1][0]) 

Output:
K
A

Help?

Thanks in advance :)

Could you provide more of the code? This is a bit too scant to troubleshoot.
