Tuple comprehension to for loop help

[jsuh21]

Thank you for your reply.
I was finally able to get some meaningful help from the class.

def get_password_leaks_count(hashes, hash_to_check):
    splithashes = hashes.text.splitlines()
    newlist = []
    for line in splithashes:
        newlist.append(line.split(':'))
        for h, count in newlist:
            if h == hash_to_check:
                return count
        return 0
        print(h, count)

However, there is a weird problem now. Last night, this functioned well just like the original, but today, it is just letting any password pass by as being safe.
