Make an issue on github using API V3 and Python

make_github_issue.py

import json
import requests

# Authentication for user filing issue (must have read/write access to
# repository to add issue to)
USERNAME = 'CHANGEME'
PASSWORD = 'CHANGEME'

# The repository to add this issue to
REPO_OWNER = 'CHANGEME'
REPO_NAME = 'CHANGEME'

def make_github_issue(title, body=None, assignee=None, milestone=None, labels=None):
    '''Create an issue on github.com using the given parameters.'''
    # Our url to create issues via POST
    url = 'https://api.github.com/repos/%s/%s/issues' % (REPO_OWNER, REPO_NAME)
    # Create an authenticated session to create the issue
    session = requests.session(auth=(USERNAME, PASSWORD))
    # Create our issue
    issue = {'title': title,
             'body': body,
             'assignee': assignee,
             'milestone': milestone,
             'labels': labels}
    # Add the issue to our repository
    r = session.post(url, json.dumps(issue))
    if r.status_code == 201:
        print 'Successfully created Issue "%s"' % title
    else:
        print 'Could not create Issue "%s"' % title
        print 'Response:', r.content

make_github_issue('Issue Title', 'Body text', 'assigned_user', 3, ['bug'])

Hi, Do you have an updated version of it?
For example: session = requests.session(auth=(USERNAME, PASSWORD)) is not working with an error: TypeError: session() takes no arguments (1 given)

I changed it to "session = requests.Session(auth=(USERNAME, PASSWORD)) " and still it fails with an error: TypeError: init() got an unexpected keyword argument 'auth'

any help is much appreciated.

Fixed the problem:
session = requests.Session()
session.auth = (USERNAME, PASSWORD)

Works great with the fix by nikhilgupta10 and I needed to set milestone to None
milestone=None

also 'labels': []

assignee has been deprecated in the latest release of API. This is the updated code that worked for me:

import os
import json
import requests

# Authentication for user filing issue (must have read/write access to
# repository to add issue to)
USERNAME = 'billkarma-bot'
PASSWORD = os.environ['BILLKARMA_BOT_GITHUB_PASSWORD']

# The repository to add this issue to
REPO_OWNER = 'footbits'
REPO_NAME = 'billkarma-ios'

def make_github_issue(title, body=None, labels=None):
    '''Create an issue on github.com using the given parameters.'''
    # Our url to create issues via POST
    url = 'https://api.github.com/repos/%s/%s/issues' % (REPO_OWNER, REPO_NAME)
    # Create an authenticated session to create the issue
    session = requests.Session()
    session.auth = (USERNAME, PASSWORD)
    # Create our issue
    issue = {'title': title,
             'body': body,
             'labels': labels}
    # Add the issue to our repository
    r = session.post(url, json.dumps(issue))
    if r.status_code == 201:
        print 'Successfully created Issue "%s"' % title
    else:
        print 'Could not create Issue "%s"' % title
        print 'Response:', r.content

make_github_issue('Issue Title', 'Body text', ['bug'])

print format is changed on python3. This works for me.

import os
import json
import requests

# Authentication for user filing issue (must have read/write access to
# repository to add issue to)
USERNAME = 'CHANGEME'
PASSWORD = 'CHANGEME'

# The repository to add this issue to
REPO_OWNER = 'CHANGEME'
REPO_NAME = 'CHANGEME'

def make_github_issue(title, body=None, labels=None):
    '''Create an issue on github.com using the given parameters.'''
    # Our url to create issues via POST
    url = 'https://api.github.com/repos/%s/%s/issues' % (REPO_OWNER, REPO_NAME)
    # Create an authenticated session to create the issue
    session = requests.Session()
    session.auth = (USERNAME, PASSWORD)
    # Create our issue
    issue = {'title': title,
             'body': body,
             'labels': labels}
    # Add the issue to our repository
    r = session.post(url, json.dumps(issue))
    if r.status_code == 201:
        print ('Successfully created Issue {0:s}'.format(title))
    else:
        print ('Could not create Issue {0:s}'.format(title))
        print ('Response:', r.content)

Using bulk import of issues, you may cause tons of notifications as well as ban from GitHub. Use new API described at https://gist.github.com/jonmagic/5282384165e0f86ef105. Known limitation - you cannot assign more than one person to issue. New API supports issue timestamps.

in case someone still stumbles in this google high ranked code, there is an official github cli tool, still in beta but pretty: https://github.com/cli/cli/tree/v0.9.0
