Simple Python Web Browser

Demonstrates low-level HTTP(S) requests using sockets and HTML text extraction with a parser. Renders elements with TKinter.

What it does

• Performs simple HTTP/HTTPS GET requests (HTTP/1.1).
• Supports file:// and data: URLs.
• Supports view-source: prefix to show HTML source with angle brackets escaped. (Only for url.py)
• Supports chunking and gzip compression.
• Automatically follows redirects.

Requirements

• Python 3.7+ (f-strings and ssl.create_default_context).
• Network access for HTTP/HTTPS.

How to run

From the repository root (where browser.py is located), run:

# Fetch a website over HTTP
python3 browser.py "http://example.org/"

# Fetch a website over HTTPS
python3 browser.py "https://example.org/"

# Open a local file (absolute path expected after file://)
python3 browser.py "file:///home/you/path/to/file.html"

# data URI (plain text)
python3 browser.py "data:text/plain,Hello%20world"

# data URI (base64)
python3 browser.py "data:text/plain;base64,SGVsbG8gV29ybGQh"

# View the source (angle brackets escaped)
python3 browser.py "view-source:http://example.org/"
