<br>
I made a Python3 module that allows users to use certain Linux shell commands from Python3 more easily than using os.system(), subprocess.Popen(), or subprocess.getoutput(). This module (once placed with the other modules) can be used like this<br>
<br>
import boash; <a href="http://boash.ls" target="_blank">boash.ls</a>()<br>
<br>
I attached the module. I plan to release it on the Internet soon, but feel free to use it now. It is licensed under LGPLv3.<br>
<br>
The name comes from combining "Boa" with "SHell". Notice that the module's name almost looks like "BASH", a common Linux shell. The Boa is a constrictor snake. This module makes Unix shells easier to use via Python3. This brings the system shell closer to the Python shell.<br>
