A short script to obtain saved Wi-Fi passwords using Python

get_network_password.py

"""
Program to find the password of a saved Wi-Fi network on your device
Compatible with Windows, Mac, and Linux

Developed by Skyascii (github.com/savioxavier)

How to use:
0. Make sure you have Python 3 installed
1. Open a terminal (eg: cmd, PowerShell, bash, zsh etc)
2. Run the program using python get_network_password.py (python3 get_network_password.py on Linux)
3. The password will be printed to the terminal, if it exists and is saved on your device

Not exactly good code, but it works fine for me. You're welcome to improve it.
