Are there any good syntax or style checkers recommended?
There is a couple. Use them all: - Ruff. Awesome linter for python. Very fast and supports a lot of rules. I recommend to configure it yourself - Black. For code formating. Not so awesome, but it will keep your code (and your teammates, if you add it to your CI pipline) sane and PEP8 - MyPy. For static type checking. If you write type hints it will help find you type-related errors before running your code More on reddit.com

Can a plagiarism detector be used for accurately checking code?

If I was a professor I would hope your code is very similar to mine. That would mean you're using excellent naming conventions and such.

I think the tool is full of shit.

Why is a Python code checker vital to secure development?

Within DevSecOps practices, the principle of โ€œshifting leftโ€ emphasizes addressing security risks earlier in the development workflow. Integrating the Snyk Python code checker into the CI/CD pipeline is considered a standard best practice for achieving this. When static analysis is embedded directly into the IDE, developers receive immediate feedback on potential Python vulnerabilities, enabling them to mitigate risks at the point of introduction and strengthen overall application security.

What are the benefits of an AI-powered Python code checker?

Snyk AI-driven Python code analysis tool enables organizations to identify and resolve complex coding vulnerabilities earlier in the secure software development lifecycle (SSDLC). These systems leverage machine learning models trained on extensive datasets of open-source projects, capturing symbolic rules that map potential flaws to effective remediations. By drawing on this collective intelligence, AI-based analyzers can detect both security and quality issues that may be overlooked during traditional peer reviews or pair programming sessions. This capability ensures that developers can remediate problems at the earliest stages, reducing the likelihood of defects propagating into production environments and impacting end-users.

Python Code Checker - Online syntax check
You can test your Python code online directly in your browser. If a syntax error is detected, then the line in error is highlighted, and it jumps to it to save time (no need to search the line). It can be useful to make online test to save time (deployment ...). Note: This tool no longer offers sandbox, it was not good enough. Python is an interpreted programming language, it features a dynamic type system and automatic memory management (garbage collector). Python is available for many operating systems.It has a large standard library.
