How to Retrieve File Content from GitHub Using Python?

Estimated read time 2 min read

To retrieve file content from GitHub using Python, you can utilize the GitHub API and the requests library. Here’s an example of how you can retrieve file content from GitHub:

  1. Install the requests library if you haven’t already done so. You can install it using pip with the command: pip install requests.
  2. Import the requests module:
import requests
  1. Define the GitHub repository, file path, and the branch or commit hash:
repository = "owner/repository"  # Replace with the GitHub repository in the format 'owner/repository'
file_path = "path/to/file.txt"  # Replace with the file path within the repository
branch = "main"  # Replace with the branch or commit hash you want to retrieve the file from
  1. Construct the API endpoint URL:
api_url = f"{repository}/contents/{file_path}?ref={branch}"
  1. Send a GET request to the GitHub API:
response = requests.get(api_url)
  1. Retrieve the file content from the response:
if response.status_code == 200:
    content = response.json().get("content")
    file_content = content.decode("base64")  # Decode the base64-encoded content
    print("File retrieval failed. Status code:", response.status_code)

In this example, we construct the GitHub API endpoint URL using the repository, file path, and branch or commit hash. The requests.get() method sends a GET request to the API endpoint.

If the response status code is 200 (indicating a successful request), we retrieve the file content from the response. The content is base64-encoded, so we decode it using the base64 module.

Finally, we print the retrieved file content. If the file retrieval fails, we print the response status code.

Remember to replace 'owner/repository' with the actual owner and repository name on GitHub, 'path/to/file.txt' with the file path within the repository, and 'main' with the desired branch or commit hash.

Please note that to access private repositories or to perform authenticated actions, you may need to provide appropriate authentication headers or tokens in the request. Refer to the GitHub API documentation for more details on authentication and other available endpoints.
