python linting in visual studio code
linting is a static code analysis tool that helps you find potential errors and enforce coding standards in your code. python linting in visual studio code (vs code) can be achieved using various extensions, with the most popular being *pylint* and **flake8**. this tutorial will guide you through setting up linting in vs code for python, with examples to illustrate its use.
step 1: install visual studio code
if you haven’t already, download and install visual studio code from [the official website](https://code.visualstudio.com/).
step 2: install python extension for vs code
1. open vs code.
2. go to the extensions view by clicking on the extensions icon in the activity bar on the side of the window or by pressing `ctrl+shift+x`.
3. search for "python" and install the extension provided by microsoft.
step 3: install a linter
you can choose between several linters for python. here, we'll cover how to set up *pylint* and **flake8**.
#### a. setting up pylint
1. open a terminal in vs code (`ctrl+``).
2. make sure you have `pip` installed, then run the following command to install pylint:
3. once installed, pylint will be automatically detected by the python extension.
#### b. setting up flake8
1. open a terminal in vs code.
2. run the following command to install flake8:
3. flake8 will also be automatically detected by the python extension.
step 4: configure linting in vs code
1. open the command palette (`ctrl+shift+p`).
2. type `python: select linter` and select it.
3. choose either pylint or flake8 from the list.
step 5: create a python file and write some code
create a new python file (e.g., `example.py`) and write some code that contains both linting errors and good practices. here’s a sample code snippet:
step 6: linting in action
1. save your file.
2. if you have pylint or flake8 set up, you should see linting warnings and errors in the problems panel (view - prob ...
