This is a telegram bot that interacts with Google Sheets and allows you to add, delete, make an expense list and show various graphs.

While I do not use Telegram, it makes sense in the context of figuring out how to interact with a GSheet using its API and a chat interface. If nothing else, its instructions for setting up API access to GSheets makes it useful.

Telegram is a popular messaging application. This library is meant to make it easy for you to write Python programs that can interact with Telegram. Think of it as a wrapper that has already done the heavy job for you, so you can focus on developing an application. Designed for use with a user or a bot account (bot API alternative).
