Python compare two large file wordlists and print if match

Let’s say I have two large files. One is md5_db.txt and second is hash list hash.txt.

md5_db.txt contains hash and pass:

hash.txt

Now I want to compare them and find the hash and if it matches in both files, print the hash with password. I’ve been trying to find the most effective solution but I get close and then it doesn’t work as wanted. The code I have is very simple, it doesn’t work yet, unless I will split the hash from password, then it will find match. Basically in nutshell I need the script to grab the hash.txt and compare it to md5_db.txt and print if matched.

with open('md5_db.txt', 'r') as file1:
    with open('hash.txt', 'r') as file2:
        same = set(line.strip() for line in file1)
        same = "n".join(same)

        for line in file2:
            word = line
            if word in same:
                print(word)

with open('md5_db.txt') as md5_db_file:
    md5_db = dict(line.strip().split(":", 1)
                  for line in md5_db_file
                  if line.strip())

with open('hash.txt') as hash_file:
    for line in hash_file:
        h = line.strip()
        if h in md5_db:
            print(h, md5_db[h])

dct = dict()
with open('md5_db.txt', 'r') as md5_file, open('hash.txt', 'r') as hash_file:
    for line in md5_file:
        hash_passw = line[:-1].split(':')
        dct[hash_passw[0]] = hash_passw[1]
    print(dct)
    for hash in hash_file:
        passw = dct.get(hash[:-1])
        if passw:
            print(hash[:-1], passw)
