Since we're using six.moves to import parse_qs, we don't need to check for an import exception, we can just import it directly.

This class abstracts the `pagination of the API <http://developer.github.com/v3/#pagination>`_.
|
|
|
|
You can simply enumerate through instances of this class::
|
|
|
|
for repo in user.get_repos():
|
|
print(repo.name)
|
|
|
|
If you want to know the total number of items in the list::
|
|
|
|
print(user.get_repos().totalCount)
|
|
print(len(user.get_repos()))
|
|
|
|
You can also index them or take slices::
|
|
|
|
second_repo = user.get_repos()[1]
|
|
first_repos = user.get_repos()[:10]
|
|
|
|
If you want to iterate in reversed order, just do::
|
|
|
|
for repo in user.get_repos().reversed:
|
|
print(repo.name)
|
|
|
|
And if you really need it, you can explicitly access a specific page::
|
|
|
|
some_repos = user.get_repos().get_page(0)
|
|
some_other_repos = user.get_repos().get_page(3)
