[Python] I made a bot that tells me the current temperature when I enter a place name on LINE

The finished product looks like this. It also supports place names that you have never heard of. If there is no spill in the place name → Geocoder → Dark Sky, it will be displayed. Personally, I always want to check Vostok Station.

Referenced Qiita page, account acquisition procedure, I will gradually add to it, such as deploying to Heroku.

About the environment etc. ・ Windows 10 ・ Python 3.7.5 ・ Heroku ・ Git ・ Line developer account ・ Darksky API

I created 4 files Procfile requirements.txt runtime.txt python:main.py

Errors etc. have not been processed. Let's do it soon ...

Information as of April 2020 DarkSky has been acquired by Apple and new APIs are no longer accepted. The service will be until the end of 2021 (crying) It will be necessary to verify whether the OpenWetherMap API can be used as an alternative.
