Github3 How To Examples in Python

In this tutorial, we will explore various examples to demonstrate the usage of the github3 library in Python. github3 is a Python library for interacting with the GitHub API v3.

Before we begin, make sure you have github3 installed. You can install it using pip:

pip install github3.py

Now, let's dive into the examples!

Example 1: Create a Repository

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Create a new repository
repo = session.create_repository('my_repository', description='My first repository')

# Print the repository details
print('Repository Name:', repo.name)
print('Description:', repo.description)
print('URL:', repo.url)

Expected Output:

Repository Name: my_repository
Description: My first repository
URL: https://github.com/your_username/my_repository

Explanation: In this example, we create a new repository on GitHub using the create_repository method. We provide the repository name and an optional description. After creating the repository, we print its details such as name, description, and URL.

Example 2: Get Repository Details

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Get a repository by name
repo = session.repository('your_username', 'my_repository')

# Print the repository details
print('Repository Name:', repo.name)
print('Description:', repo.description)
print('URL:', repo.url)
print('Owner:', repo.owner.login)
print('Number of Stars:', repo.stargazers_count)
print('Number of Forks:', repo.forks_count)

Expected Output:

Repository Name: my_repository
Description: My first repository
URL: https://github.com/your_username/my_repository
Owner: your_username
Number of Stars: 5
Number of Forks: 2

Explanation: In this example, we retrieve the details of an existing repository by providing the owner's username and repository name. We then print various details of the repository, including its name, description, URL, owner's username, number of stars, and number of forks.

Example 3: List Repository Issues

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Get a repository by name
repo = session.repository('your_username', 'my_repository')

# List all open issues in the repository
issues = repo.issues(state='open')

# Print the issue titles
for issue in issues:
    print(issue.title)

Expected Output:

Issue 1: Fix bug in login form
Issue 2: Update README with instructions

Explanation: In this example, we retrieve all the open issues in a repository using the issues method. We can specify the state of the issues (e.g., 'open', 'closed') as an optional parameter. Then, we iterate over the issues and print their titles.

Example 4: Create an Issue

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Get a repository by name
repo = session.repository('your_username', 'my_repository')

# Create a new issue
issue = repo.create_issue(title='Bug in login form', body='There is a bug in the login form.')

# Print the issue details
print('Issue Title:', issue.title)
print('Issue Body:', issue.body)
print('Issue URL:', issue.html_url)

Expected Output:

Issue Title: Bug in login form
Issue Body: There is a bug in the login form.
Issue URL: https://github.com/your_username/my_repository/issues/1

Explanation: In this example, we create a new issue in a repository using the create_issue method. We provide the issue title and an optional body. After creating the issue, we print its details such as title, body, and URL.

Example 5: List Repository Commits

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Get a repository by name
repo = session.repository('your_username', 'my_repository')

# List all commits in the repository
commits = repo.commits()

# Print the commit messages
for commit in commits:
    print(commit.commit.message)

Expected Output:

Commit 1: Fix typo in README
Commit 2: Update login form validation

Explanation: In this example, we retrieve all the commits in a repository using the commits method. Then, we iterate over the commits and print their messages.

Example 6: Create a Pull Request

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Get a repository by name
repo = session.repository('your_username', 'my_repository')

# Create a new pull request
pull_request = repo.create_pull(title='Fix typo in README', body='There is a typo in the README file.')

# Print the pull request details
print('Pull Request Title:', pull_request.title)
print('Pull Request Body:', pull_request.body)
print('Pull Request URL:', pull_request.html_url)

Expected Output:

Pull Request Title: Fix typo in README
Pull Request Body: There is a typo in the README file.
Pull Request URL: https://github.com/your_username/my_repository/pull/1

Explanation: In this example, we create a new pull request in a repository using the create_pull method. We provide the pull request title and an optional body. After creating the pull request, we print its details such as title, body, and URL.

Example 7: List Repository Releases

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Get a repository by name
repo = session.repository('your_username', 'my_repository')

# List all releases in the repository
releases = repo.releases()

# Print the release names
for release in releases:
    print(release.name)

Expected Output:

Release 1.0
Release 2.0

Explanation: In this example, we retrieve all the releases in a repository using the releases method. Then, we iterate over the releases and print their names.

Example 8: Upload a Release Asset

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Get a repository by name
repo = session.repository('your_username', 'my_repository')

# Get the release by tag name
release = repo.release_from_tag('v1.0')

# Upload a release asset
asset = release.upload_asset('path/to/file.zip', 'application/zip')

# Print the asset details
print('Asset Name:', asset.name)
print('Asset URL:', asset.browser_download_url)

Expected Output:

Asset Name: file.zip
Asset URL: https://github.com/your_username/my_repository/releases/download/v1.0/file.zip

Explanation: In this example, we upload a release asset (e.g., a file) to a specific release in a repository using the upload_asset method. We provide the path to the file and its content type. After uploading the asset, we print its details such as name and download URL.

Example 9: List Repository Collaborators

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Get a repository by name
repo = session.repository('your_username', 'my_repository')

# List all collaborators in the repository
collaborators = repo.collaborators()

# Print the collaborator usernames
for collaborator in collaborators:
    print(collaborator.login)

Expected Output:

user1
user2

Explanation: In this example, we retrieve all the collaborators of a repository using the collaborators method. Then, we iterate over the collaborators and print their usernames.

Example 10: Add Collaborator to a Repository

import github3

# Create a GitHub session
session = github3.login('your_username', 'your_password')

# Get a repository by name
repo = session.repository('your_username', 'my_repository')

# Add a collaborator to the repository
repo.add_collaborator('new_user')

# List all collaborators in the repository
collaborators = repo.collaborators()

# Print the collaborator usernames
for collaborator in collaborators:
    print(collaborator.login)

Expected Output:

user1
user2
new_user

Explanation: In this example, we add a collaborator to a repository using the add_collaborator method. We provide the username of the collaborator to be added. After adding the collaborator, we retrieve all the collaborators of the repository and print their usernames.

These examples cover a range of common operations that can be performed using the github3 library in Python. You can explore the library further by referring to the official documentation.

Note: Replace 'your_username' and 'your_password' with your GitHub username and password. It is recommended to use an access token instead of a password for authentication.
