Source: https://github.com/zedgr/pychallonge/blob/master/README.md

Demonstrates how to set API credentials, retrieve tournament details by ID, list participants for a tournament, and start a tournament. All data is returned as Python dictionaries.

```python
import challonge

# Tell pychallonge about your CHALLONGE! API credentials.
challonge.set_credentials("your_challonge_username", "your_api_key")

# Retrieve a tournament by its id (or its url).
tournament = challonge.tournaments.show(3272)

# Tournaments, matches, and participants are all represented as normal Python dicts.
print(tournament["id"])
print(tournament["name"])
print(tournament["started_at"])

# Retrieve the participants for a given tournament.
participants = challonge.participants.index(tournament["id"])
print(len(participants))

# Start the tournament and retrieve the updated information to see the effects
# of the change.
challonge.tournaments.start(tournament["id"])
tournament = challonge.tournaments.show(tournament["id"])
