Python IDE Environment

Python development with FastAPI, Flask, Django, data science tools, and pre-activated virtual environment.

What's Inside

Tool	Version	Purpose
Python	3.x	Runtime
pip	Latest	Package manager
FastAPI	Latest	Modern async web framework
Flask	Latest	Lightweight web framework
Django	Latest	Full-featured web framework
numpy / pandas	Latest	Data science libraries
Jupyter / IPython	Latest	Interactive notebooks

Quick Start

# Run a Python file
py-run app.py

# Run tests
py-test

# Start a FastAPI server
py-serve app:app

# Start Jupyter notebook
py-jupyter

# Create a new project
py-init my-project

Helper Commands

Command	What it does
`py-run <file>`	Run a Python file
`py-test`	Run pytest
`py-serve app:app`	Start FastAPI/Flask with uvicorn
`py-jupyter`	Start Jupyter notebook server
`py-init <name>`	Scaffold a Python project
`py-lint`	Run ruff + mypy on current directory
`py-help`	Show all available commands

Virtual Environment

The environment comes with a pre-activated virtual environment. You don't need to create one — just use pip install directly:

pip install requests
pip install fastapi uvicorn

This avoids the externally-managed-environment error (PEP 668) that you'd normally see on modern Python.

Tips

The virtual environment is at /opt/learncen-venv/ and is always active
py-run without arguments runs main.py if it exists, or app.py
py-serve uses uvicorn with auto-reload — great for development
py-jupyter starts on port 8888 with no token required
VS Code is pre-configured to use the correct Python interpreter
Ctrl+Shift+B runs the current file

Security

Root access is restricted. Use sudo apt install <package> for system packages.
pip and python3 are whitelisted for sudo access.
