Learning Objectives

At the end of this project, you are expected to be able to explain to anyone, without the help of Google:

General

  • How to fetch internet resources with the Python package urllib
  • How to decode urllib body response
  • How to use the Python package requests #requestsiswaysimplerthanurllib
  • How to make HTTP GET request
  • How to make HTTP POST/PUT/etc. request
  • How to fetch JSON resources
  • How to manipulate data from an external service

Requirements

General

  • Allowed editors: vi, vim, emacs`
  • All your files will be interpreted/compiled on Ubuntu 20.04 LTS using python3 (version 3.8.5)
  • All your files should end with a new line
  • The first line of all your files should be exactly #!/usr/bin/python3
  • A README.md file at the root of the repo, containing a description of the repository
  • A README.md file, at the root of the folder of this project, is mandatory
  • Your code should use the pycodestyle (version 2.8.*)
  • All your files must be executable
  • The length of your files will be tested using wc
  • All your modules should have a documentation (python3 -c 'print(__import__("my_module").__doc__)')
  • You must use get to access to dictionary value by key (it won’t throw an exception if the key doesn’t exist in the dictionary)
  • A documentation is not a simple word, it’s a real sentence explaining what’s the purpose of the module, class or method (the length of it will be verified)
  • Your code should not be executed when imported (by using if __name__ == "__main__":)

10. Time for an interview!

The Holberton School staff evaluates candidates applying for a back-end position with multiple technical challenges, like this one:

Please list 10 commits (from the most recent to oldest) of the repository “rails” by the user “rails”
You must use the GitHub API, here is the documentation https://developer.github.com/v3/repos/commits/
Print all commits by: `<sha>: <author name>` (one by line)

Write a Python script that takes 2 arguments in order to solve this challenge.

  • The first argument will be the repository name
  • The second argument will be the owner name
  • You must use the packages requests and sys
  • You are not allowed to import packages other than requests and sys
  • You don’t need to check arguments passed to the script (number or type)

Only 17% of applicants for a backend position at Holberton finished this task in less than 15 minutes.
