Using github API

Github is well known web service for source code management and distributed revision control. Github API provide various HTTP methods thrught which one can access details of a contribuotr, repo, organization etc.

Here I am using the same github API to know how much percentage a contributor has contributed to his repos, using number of commits. There are various wrapper libraries available in different languages to access this API, but here I am using only real github API and python request library to do the job.

Getting contributors github handler

In [2]:
import requests

username = raw_input("Enter github handler: ")
Enter github handler: exploreshaifali

Basic Info of the contrbutor

Now first lets fetch all basic infro of the contributor and print them. For this we need to make an HTTP call to url "" this will return json data about user. We can use that data easily converting it into python dictonary.

In [3]:
def get_user_info(username):
    """ Getting basic user infos: Step 1 
        username : u'login'
        real name: u'name'
        gravtar : u'avatar_url' 
        numbre of public repos
        email: u'email'
        github url: u'url'
    url = ""+username
    r = requests.get(url).json()
    print('username: {username} \n Real Name: {real_name} \n \

Details of public repos

Now lets fetch and print details of each public repo the contriboutor have
