[PYTHON] I made a slack bot that notifies me of the temperature

Get a token for Open Weather Map

Create an account at http://openweathermap.org/ and get API_KEY on the api_keys screen.

Get a token for Slack bot testing

The explanation of how to get the bot token is given in the slack api manual.

Reference URL: https://api.slack.com/bot-users

Program example

In this program, the latitude and longitude are specified and the temperature in the corresponding area is acquired.

In bot.py, the process of actually getting the temperature and tweeting it on the slack channel is described. Open Weather Map, slack token, etc. are set in settings.py.
