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.

python-requests/2.31.0
How to Control Python-requests
Block Completely
To prevent Python-requests from accessing your entire website, add this to your robots.txt file:
# Block Python-requests
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:

Detection Patterns
Multiple ways to detect Python-requests in your application:
Basic Pattern
/Python\-requests/iStrict Pattern
/^python\-requests/2\.31\.0$/Flexible Pattern
/Python\-requests[\s\/]?[\d\.]*?/iVendor Match
/.*Python.*Python\-requests/iImplementation Examples
// PHP Detection for Python-requests
function detect_python_requests() {
$user_agent = $_SERVER['HTTP_USER_AGENT'] ?? '';
$pattern = '/Python\\-requests/i';
if (preg_match($pattern, $user_agent)) {
// Log the detection
error_log('Python-requests detected from IP: ' . $_SERVER['REMOTE_ADDR']);
// Set cache headers
header('Cache-Control: public, max-age=3600');
header('X-Robots-Tag: noarchive');
// Optional: Serve cached version
if (file_exists('cache/' . md5($_SERVER['REQUEST_URI']) . '.html')) {
readfile('cache/' . md5($_SERVER['REQUEST_URI']) . '.html');
exit;
}
return true;
}
return false;
}

Should You Block This Bot?
Recommendations based on your website type:
| Site Type | Recommendation | Reasoning |
|---|---|---|
| E-commerce | Optional | Evaluate based on bandwidth usage vs. benefits |
| Blog/News | Allow | Increases content reach and discoverability |
| SaaS Application | Block | No benefit for application interfaces; preserve resources |
| Documentation | Selective | Allow for public docs, block for internal docs |
| Corporate Site | Limit | Allow for public pages, block sensitive areas like intranets |
