Understanding Requests with Caching in Python

If you are working on a project that involves sending requests to an API or a website, you may encounter slow response times or even encounter errors when the website or API is down. One way to solve this issue is by implementing caching in your Python code.

What is Caching?

Caching is a process of storing data temporarily in a cache so that it can be retrieved faster when needed. In Python, you can implement caching using the built-in caching libraries or third-party libraries such as Redis.

How to Implement Caching with Requests in Python?

The requests library is a popular Python library that allows you to send HTTP requests with ease. To implement caching with requests in Python, you can use the cache_control parameter.

Here is an example of how to use the cache_control parameter to implement caching:

import requests

response = requests.get('', cache_control={'max-age': 60})


In the above code, we are sending a GET request to with a caching time of 60 seconds using the cache_control parameter. The max-age parameter specifies the maximum amount of time that the response can be cached.

Other Ways to Implement Caching in Python

Besides using the cache_control parameter, there are other ways to implement caching in Python. Some of these methods include:

  • Using a caching library such as Redis or Memcached.
  • Using the Python functools.lru_cache decorator to cache function results.
  • Using the Python diskcache library to implement disk-based caching.


Caching is an important technique for improving the performance of your Python code when working with APIs and websites. By implementing caching, you can reduce the number of requests made to the API or website, which can result in faster response times and fewer errors. Use the above methods to implement caching in your Python code and see the difference it makes!
