Retrieving User Repositories Using Github Api With Little Help of Python 3
There are different ways to retrieve user repositories; one such is using Python libraries, but they usually need your API keys even though your repository is public. We could do this by using GitHub’s API v3 HTTP request.
For example, to retrieve my public libraries I would use https://api.github.com/users/akshaybabloo/repos, this returns a JSON array; we just have to use the Python’s json standard library to get the desired key-value pairs (in Python’s terminology - Dictionary).
Code
Lets build a custom iterator for the class GitHubRepo.
class GitHubRepo:
def __init__(self):
response = urlopen(DEFAULT_BASE_URL) # Open the url
data = response.read().decode("utf-8") # Encode the content as UTF-8
self.data = json.loads(data) # Load the JSON list
self.index = len(self.data) # Get the length of the JSOn list
del response # Delete unused variable (Optional)
del data # Delete unused variable (Optional)
def __iter__(self):
"""
Creating an iterator, which returns itself.
"""
return self
def __next__(self):
"""
Continues the loop until the index reaches 0.
"""
if self.index == 0:
raise StopIteration
self.index -= 1
return self.data[self.index]
iter and next are the built-in iterator types.
You are essentially making the GitHubRepo object loopable, for example, let us consider the following snippet:
>>> x = [1, 2, 3]
>>> y = iter(x)
>>> next(y)
1
>>> next(y)
2
>>> next(y)
3
>>> next(y)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
StopIteration
Once there are no more indexes to reach, the program raises a StopIteration exception and exits. The above terminal code can be written as:
x = [1, 2, 3]
for y in x:
print(y)
# 1
# 2
# 3
GitHub JSON structure The next thing you should know is the structure of the JSON Objects that is requested from GitHub.

Once you know what information you want from the JSON Object, just call by its key, for example, using the same GitHubRepo class we could do the following:
repo = GitHubRepo()
for data in repo:
print(data['name'])
# In my case it will print:
