In a world where technology is advancing every minute, it is essential to keep up with the latest software for better performance. One of the most widely used computer programming languages is Python. Python has gained immense popularity for its user-friendliness and versatility. It is an open-source programming language that allows the creation of various desktop applications, web applications, game development, and much more. One of the essential tasks involving extracted files is unpacking files.

What are 7z files?

7z files are compressed files with high compression ratios that belong to the 7-Zip file archive format. This format offers better compression than others like ZIP or RAR, making it more popular among users. These archives contain one or more files or folders, packed together, creating a smaller size for the file or folder. However, these files need to be unpacked to access their contents.

Why use Python for unpacking 7z files?

Python is a versatile, easy-to-use programming language that can simplify many tasks. Unpacking 7z files is no exception. The use of Python for this purpose results in a simple, single-command solution using the python lzma module, which comes installed with Python itself, removing the need for additional dependencies or software.

How to unpack 7z files easily with Python?

The process of unpacking 7z files is relatively simple when using Python. Here are the steps to follow:

Step 1: Import the required libraries

The first step is to import the required libraries or modules needed for the task, including lzma.

Step 2: Open the 7z file using Python

The second step is to open the 7z file, which can be done using the Python open function.

Step 3: Extract the contents of the compressed file

The third step is to extract the contents of the compressed file using the lzma library. This can be done using the method to read the contents of the file and lzma.decompress() method to extract the contents..

Step 4: Write the extracted content to disk

The fourth and final step is to write the extracted content to disk using the Python open() function and specifying the file path as well as the write mode.
