PyScript allows you to run Python code directly in your web browser without any server-side processing.

Key Features:

Zero Server Setup: Python runs entirely in the browser using WebAssembly
Standard Library Access: Use familiar Python modules like datetime, sys, and more
Simple Integration: Add Python with just a tag
External Scripts: Load Python code from files using the src attribute
Console Output: View results in the browser console or write to the DOM

The Examples:

Example 1: Classic "Hello World" - The simplest PyScript program
Example 2: Current date/time - Demonstrates external Python scripts and datetime module
Example 3: Fibonacci sequence - Shows algorithmic computation and list comprehension
Example 4: Snake traversal - Matrix manipulation and DOM manipulation from Python

Getting Started:

The basic pattern for running Python in the browser is simple:

<script type="py">
  print("Hello from Python!")
</script>

<!-- Or load from a file -->
<script type="py" src="/path/to/script.py"></script>
