Dancing with Python

By: Robert S. Sutor

Overview of this book

Dancing with Python helps you learn Python and quantum computing in a practical way. It will help you explore how to work with numbers, strings, collections, iterators, and files. The book goes beyond functions and classes and teaches you to use Python and Qiskit to create gates and circuits for classical and quantum computing. Learn how quantum extends traditional techniques using the Grover Search Algorithm and the code that implements it. Dive into some advanced and widely used applications of Python and revisit strings with more sophisticated tools, such as regular expressions and basic natural language processing (NLP). The final chapters introduce you to data analysis, visualizations, and supervised and unsupervised machine learning. By the end of the book, you will be proficient in programming the latest and most powerful quantum computers, the Pythonic way.

A.12 Linting

A linter is an application that scans your code looking for errors or variations from stylistic conventions. Many IDEs like Visual Studio Code have built-in support for one or more linters. [VSL] A linter does static analysis in that it does not run your code and only looks at what you have written.

A linter usually has three classes of messages:

  • Informational – “You might want to know about this, but you will likely get annoyed if I keep telling you.”
  • Warning – “You did something here that might cause problems, or you are not following formatting conventions. Don’t procrastinate, and take a look now.”
  • Error – “Fix this. Now.”

A good Python linter to start with is pylint. Install it via:

pip install pylint

Once you have it installed, issuing pylint --help from the operating...
