I started writing some python code that adds events to a spreadsheet in Google Sheets using gdata. Everything went well and it works, but now I wanted to add these same events to a calendar and I can't figure out what I'm supposed to use. 
I see that the calendar API on Google is at V3 and they suggest I install google-api-python-client. Gdata seems to be almost abandoned and I feel like I'm lost in the middle.
I would just like to be able to use one python API to add data to a calendar and a spreadsheet and if possible keeping things simple as I'm really not very good at this yet. Any help would be greatly appreciated. Thanks
You'll need to continue to use gdata for sheets until a new version that supports Google API is released.
