What is Python-requests?
Python-requests is the default user agent for the popular Python Requests library, known for its human-friendly HTTP interface. This user agent is more common than urllib as Requests has become the de facto standard for HTTP operations in Python. It appears in logs from various applications including web scrapers, API clients, and monitoring tools. The Requests library's ease of use has made it popular among developers, data scientists, and researchers. While often used legitimately, some websites monitor this user agent for potential automated access.

How to Control Python-requests
Block Completely
To prevent Python-requests from accessing your entire website, add this to your robots.txt file:
User-agent: python-requests
Disallow: /
Block Specific Directories
To restrict access to certain parts of your site while allowing others:
User-agent: python-requests
Disallow: /admin/
Disallow: /private/
Disallow: /wp-admin/
Allow: /public/
Set Crawl Delay
To slow down the crawl rate (note: not all bots respect this directive):
User-agent: python-requests
Crawl-delay: 10
How to Verify Python-requests
Verification Method:
Requests library default user agent

Detection Patterns
Multiple ways to detect Python-requests in your application:
Basic Pattern
/Python\-requests/i
Strict Pattern
/^python\-requests/2\.31\.0$/
Flexible Pattern
/Python\-requests[\s\/]?[\d\.]*?/i
Vendor Match
/.*Python.*Python\-requests/i
Implementation Examples
PHP
Python
JavaScript
.htaccess
Nginx
