i can not think of a universal method for handling these different formats, but i do know two things:

1. RAR is not an open format so you'll need to use a binary from RARLabs to unarchive these files (or a 3rd party library that uses such binary)
2. python has the zipfile module for zip archives, but afaik it does not support encrypted files (password protected) edit: it can but can not create encrypted archives

[remote sundial]

def unarchive(file_path, destination, password=None):
    if password is not None:
        password = password.encode()  # convert password to bytes

    if file_path.endswith('.zip'):
        with zipfile.ZipFile(file_path, 'r') as zip_ref:
            zip_ref.extractall(destination, pwd=password)
    elif file_path.endswith('.rar'):
        with rarfile.RarFile(file_path, 'r') as rar_ref:
            rar_ref.extractall(destination, pwd=password)
    elif file_path.endswith('.7z'):
        with py7zr.SevenZipFile(file_path, mode='r', password=password) as z:
            z.extractall(destination)
    else:
        print("Unsupported file format")

Hey @remote sundial!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

if you've found a good library for each format, that is probably a fine method

[remote sundial]

does zip needs password.encode()?

because then im using password.encode(), 7z not work but .zip works

[lone onyx]

according to the python documentation, ZipFile.open requires a bytes object for the pwd argument

but you'll have to check the docs of the 7z library as well

[remote sundial]

7z works fine

not sure about rar, but i will test

i found out that in python so annoying

i though you can use 7z library and unarchive any extension archives

[lone onyx]

each archive "extension" uses a different format that needs to be supported

[remote sundial]

ye i understand, but weird that no one put all archive algos in one library
