MD5 Hash, Python 3 . How to Generate In Python

I need advice on how to get the md5 hash for a zip file. I will be constantly downloading files from an ftp using ftplib. As you know ftplib cannot tell if a file has been modified or not.

I want to use the md5 hash of each new file to tell if it has been modified or not by simply comparing the hashes after downloading the new file to tempdir. If the hashes are similar, I remove newly downloaded file. However, if hashes are different, newly downloaded file is kept, old hash is replaced with new hash and the script continues.

Please advice on how to achieve this. Are there any standalone modules for hashing md5 or similar.

Thanks.``

Very simply, in python 3.8+, I use to keep the code as quick and compact as possible.

import hashlib
file_hash = hashlib.md5(open(old_file_path,'rb').read()).hexdigest()
print(file_hash)

import hashlib
m=hashlib.md5();
m.update(open('yourzipfile.zip').read());

a=m.hexdigest()
print (a);
