Top 16 Python Code Analysis Projects

I don't understand how it's ever an actual problem and not just people being lazy / literally just starting out learning the language. Every Python-capable editor / IDE is capable of, and immediately will, notify you of any formatting issues of the sort. Python also has great, trivial to use autoformatters like black[1] that essentially all production code should use.
What realistic scenario is there where it actually makes sense deviating from the standard the language is trying to enforce?

I use https://ycm-core.github.io/YouCompleteMe/ for autocomplete and https://github.com/vim-syntastic/syntastic for syntax changing as well. For my python projects this was enough to move away from VS Code. There are other plugins I use to help me code with python with vim but this should answer most of your question.

YAPF (Yet Another Python Formatter) is Google's official python formatter which follows google's style guide. The documentation is easy to understand the installation and configuration for this formatter.

Python these days is sprouting type annotations all over the show, the benefits are too good to ignore.
And if a given library doesn't use type annotations, people will often create type stubs for it that mypy can consume.

Project mention: flake8-cached - a wrapper around flake8 to cache file runs | reddit.com/r/Python | 2021-05-20
I use flake8 with [wemake-python-style-guide](https://wemake-python-stylegui.de/) plugin. It takes around 2mins to run the linter for some mid-range web apps. I have created https://github.com/jnoortheen/flake8-cached to speed up this process. I use it with Pycharm's filewatcher. It is a simple wrapper and intended to be used only during development with a fs watcher.

Project mention: What does it mean to have -> after a function | reddit.com/r/learnpython | 2021-03-14
Indeed there are! pyannotate is probably the most popular one, authored by Guido van Rossum while he was at Dropbox.

I maintain a similar (but less popular) open-source CLI that generates flow charts for dynamic languages (Python, JS, Ruby, PHP) - https://github.com/scottrogowski/code2flow/
The thought has crossed my mind to try to actually sell it as a SaaS. But by itself, call graph visualizers are the sort of thing that you would need only once or only every once in a while. That sort of software is very difficult to monetize - as 10,000 failed productivity app companies could tell you. I don't know the details of what happened with Sourcetrail but I assume it was similar - developers might have found it useful occasionally but it's not something most developers would use daily or even monthly - so it's hard to justify a subscription.

emerge
emerge is a source code analysis tool and dependency visualizer that can be used to gather insights about source code structure, metrics, dependencies and complexity of software projects. After scanning the source code of a project it provides you an interactive web interface to explore and analyze your project by using graph structures.
Project mention: Is it possible to generate a flow diagram from Javascript code? | reddit.com/r/vscode | 2021-09-06There's no VS Code extension for it AFAIK, but it's the best (and almost only) tool that I know which can do it for JavaScript code. There's also madge and emerge, in case the first one doesn't fit your needs.
