What PyScripter is

PyScripter is a free, open-source Python integrated development environment for Windows. Its editor provides syntax highlighting, code folding, completion, call tips, and syntax checking while you type. An integrated interpreter and debugger include remote debugging, conditional breakpoints, call stacks, variable and watch views, thread debugging, and post-mortem analysis. For testing and maintenance, it offers a unit-testing interface, automatic test generation, and refactoring tools for organizing imports, renaming, and extracting functions. The file explorer integrates version control through Tortoise Git, Tortoise SVN, or Tortoise CVS, and external tools can include PyLint, TabNanny, and Profile. Built-in LLM assistance offers editor help and chat with OpenAI, Gemini, Grok, DeepSeek, and local models. OpenAI usage requires a paid plan or pay-as-you-go credit; light Gemini use is free, and Ollama runs local models. Windows users need Python 3.8 or newer. Portable zip packages require no installation after unzipping.
