Developing in the WSL with VSCode

The Windows Subsystem for Linux lets developers run a Linux environment on a Windows OS, which is considerably lighter than VMs. The following is the first post of a series that will detail the deployment of python applications in a Linux container on Azure.

I use VSCode as my preferred IDE, and a couple of extensions are necessary on this platform:

Connecting to the Windows Subsystem for Linux from VSCode is then very easy.

connectvscode

Upon selecting a project folder and opening (or creating) a python file, VSCode will ask to install the recommended extensions for python in this subsystem. Once the Python extensions are installed, the relevant interpreter can be selected.

Being a ‘new’ subsystem, python libraries must be installed. As we now have a ‘new’ subsystem, we must install python libraries. It is recommended to execute the following steps if the pip command does not work:

This should enable commands like pip install numpy to work.

As a test, we use the following simple program that adds two numpy arrays.

import numpy as  np

a=np.random.rand(3,3)
b=np.random.rand(3,3)
 
print(a)
print(b)
print(a+b)

The application can be executed by using the usual command Python: Run Python file in terminal or by keying in python3 «filename.py» in the terminal.
