Write a Python program that reads a pdb file $($either saved in the personal computer or fetch it from online servers like www$.$rcsb$.$org$),$the two options should be available to the user. If the user chooses to download the pdb file directly from online, s$/$he should be able to provide the ID of the protein and chain ID$.$

Your program should be able to find the following $($implement it as a menu$)$:

$9.$ Given a text file called sequences.txt that contains a list of IDs for proteins and a target chain, your program should globally align the chain of the protein against all chains in the list, one at a time, and report the alignment score and identity percentage. Use Blosum$62$scoring matrix and gap score$=-2.$
