Python Qt6 : tool for remove duplicate files ...

Today I created a Python script with PyQt6 that allows me to remove duplicate files based on three ways of selecting the type of duplicate.

The script also makes an estimate of the execution time...

Because the source code is relatively simple and can be very easily reconstructed with the help of artificial intelligence, I am not adding it to the posts.

Here is what the application looks like with PyQt6.

Python 3.8.5 : The hashlib python package - part 001.

The tutorial for today is about hashlib python module.
The official webpage comes for this python package has this intro:
This module implements a common interface to many different secure hash and message digest algorithms. Included are the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 (defined in FIPS 180-2) as well as RSA’s MD5 algorithm (defined in Internet RFC 1321).
The example source code to test a simple hash is this:

import hashlib
import os

def file_sha1(filename):
    BUF_SIZE = 65536  # read stuff in 64kb chunks!
    get_sha1 = hashlib.sha1()
    with open(filename, 'rb') as f:
        while True:
            data = f.read(BUF_SIZE)
            if not data:
                break
            get_sha1.update(data)
    return get_sha1.hexdigest()

# I add this comment after first to see the hash difference.
files = [f for f in os.listdir('.') if os.path.isfile(f)]
for f in files:
    h = file_sha1(f)
    print(h) 

Let's test the source code with the default directory and two files.
I run it first with default source code and then I add a comment to test_hash_file.py file.
You can see the hash is changed from b222523567a8a806382b86578717ddbd00e0f4b4 to 2134660551cc67812413a3a75fd12efb05d591ef.
