How do I clear cache with Python Requests?

Add a 'Cache-Control: no-cache' header:

self.request = requests.get('http://google.com',
                            headers={'Cache-Control': 'no-cache'})

See https://stackoverflow.com/a/55613686/469045 for complete answer.

Late answer, but python requests doesn't cache requests, you should use the Cache-Control and Pragma headers instead, i.e.:

import requests
h = {
    ...
    "Cache-Control": "no-cache",
    "Pragma": "no-cache"
}
r = requests.get("url", headers=h)
...

HTTP/Headers

• Cache-Control
  The Cache-Control general-header field is used to specify directives for caching mechanisms in both requests and responses. Caching directives are unidirectional, meaning that a given directive in a request is not implying that the same directive is to be given in the response.

• Pragma
  Implementation-specific header that may have various effects anywhere along the request-response chain. Used for backwards compatibility with HTTP/1.0 caches where the Cache-Control header is not yet present.

Directive

• no-cache
  Forces caches to submit the request to the origin server for validation before releasing a cached copy.

Note on Pragma:

Pragma is not specified for HTTP responses and is therefore not a reliable replacement for the general HTTP/1.1 Cache-Control header, although it does behave the same as Cache-Control: no-cache, if the Cache-Control header field is omitted in a request. Use Pragma only for backwards compatibility with HTTP/1.0 clients.
