Speed

Pyright is a fast type checker meant for large Python source bases. It can run in a 'watch' mode and performs fast incremental updates when files are modified.

Configurability

Pyright supports configuration files that provide granular control over settings. Different 'execution environments' can be associated with subdirectories within a source base. Each environment can specify different module search paths, python language versions, and platform targets.

Type Checking Features

  • PEP 484 type hints including generics
  • PEP 487 simpler customization of class creation
  • PEP 526 syntax for variable annotations
  • PEP 544 structural subtyping
  • PEP 561 distributing and packaging type information
  • PEP 563 postponed evaluation of annotations
  • PEP 585 type hinting generics in standard collections
  • PEP 586 literal types
  • PEP 589 typed dictionaries
  • PEP 591 final qualifier
  • PEP 593 flexible variable annotations
  • PEP 604 complementary syntax for unions
  • PEP 612 parameter specification variables
  • PEP 613 explicit type aliases
  • PEP 635 structural pattern matching
  • PEP 637 indexing with keyword arguments
  • PEP 646 variadic generics
  • PEP 647 user-defined type guards
  • PEP 655 required typed dictionary items
  • Type inference for function return values, instance variables, class variables, and globals
  • Type guards that understand conditional code flow constructs like if/else statements

VS Code Language Features

The VS Code extension supports many time-saving language features including:

  • Intelligent type completion of keywords, symbols, and import names appears when editing
  • Import statements are automatically inserted when necessary for type completions
  • Signature completion tips help when filling in arguments for a call
  • Hover over symbols to provide type information and doc strings
  • Find Definitions to quickly go to the location of a symbol’s definition
  • Find References to find all references to a symbol within a code base
  • Rename Symbol to rename all references to a symbol within a code base
  • Find Symbols within the current document or within the entire workspace
  • View call hierarchy information — calls made within a function and places where a function is called
  • Organize Imports command for automatically ordering imports according to PEP8 rules
  • Type stub generation for third-party libraries

Built-in Type Stubs

Pyright includes a recent copy of the stdlib type stubs from Typeshed. It can be configured to use another (perhaps more recent or modified) copy of the Typeshed type stubs. Of course, it also works with custom type stub files that are part of your project.

For more details, refer to the README on the Pyright GitHub site.

Pylint is a Python static code analysis tool which looks for programming errors, helps enforcing a coding standard, sniffs for code smells and offers simple refactoring suggestions. It's highly configurable, having special pragmas to control its errors and warnings from within your code, as well as from an extensive configuration file.

GitHub is where people build software. More than 40 million people use GitHub to discover, fork, and contribute to over 100 million projects.

Before using this plugin, ensure that pylint (1.0 or later) is installed on your system. To install pylint, do the following: Install Python and pip.

Pylint score

Pylint Static Code Analysis, out of 10, a detailed output on what to fix, and the ability to ignore things you do not believe in. Finally, Pylint displays a global evaluation score for the code, rated out of a maximum score of 10.0. This output can be suppressed through the --score=n option, or its shorthand version -sn. The evaluation formula can be overridden with the --evaluation=<python_expression> option.

Pylint output, The message type can be: [I]nformational messages that Pylint emits (do not contribute to your analysis score); [R]efactor for a 'good Does anyone know how to extract only the pylint score for a repository? So, assuming pylint produces the following output: Global evaluation ----- Your code has been rated at 6.67/10 (previous run: 6.67/10, +0.00) I would like it to return a value of 6.67. Thanks, Seán

Pylint, By default, the formula to calculate score is. 10.0 - ((float(5 * error + warning + refactor + convention) / statement) * 10). However, this option can be changed in​ Fully customizable. Modify your pylintrc to customize which errors or conventions are important to you. The big advantage with Pylint is that it is highly configurable, customizable, and you can easily write a small plugin to add a personal feature.

The Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations and narrative text. Uses include: data cleaning and transformation, numerical simulation, statistical modeling, data visualization, machine learning, and much more.

We recommend installing the classic Jupyter Notebook using the conda package manager. Either the miniconda or the miniforge conda distributions include a minimal conda installation. Then you can install the notebook with: conda install -c conda-forge notebook

Close Jupyter Notebooks, open Anaconda Prompt, and run the following command: pip install jupyter_contrib_nbextensions && jupyter contrib nbextension install. Once you've done that, start up a notebook and you should seen an Nbextensions tab. Clicking this tab will show you a list of available extensions.
