Python Setup

Setting Up Python

Before writing code, let's ensure you have Python properly configured.

Installation

Local Installation

  • Download Python from python.org
  • Verify installation:
python --version

Virtual Environments

Always use virtual environments for projects:

python -m venv myenv
source myenv/bin/activate  # On Windows: myenv\Scripts\activate

Installing Packages

Use pip to install packages:

pip install openai langchain

Try It Yourself

Run this code example to practice what you've learned.

example.py
1# Check Python version
2import sys
3print(f"Python version: {sys.version}")
4
5# Check if common AI packages are available
6packages = ["openai", "langchain", "httpx"]
7
8for pkg in packages:
9    try:
10        __import__(pkg)
11        print(f"✓ {pkg} is installed")
12    except ImportError:
13        print(f"✗ {pkg} is not installed")
