The nblint package allows you to run the pycodestyle engine within Jupyter Notebook. This will check your code (i.e. linting) with the pycodestyle engine.
Linting highlights any syntactical or stylistic problems in your Python code, making it less error prone and more readable to your colleagues. Linting tools were first introduced by frustrated debuggers in 1978, and the practice does indeed get its name from the act of removing small bits of stray fabric from your clothes coming out of the dryer.
