# Simple Google Drive backup script with automatic authentication
# for Google Colaboratory (Python 3)

# Instructions:
# 1. Run this cell and authenticate via the link and text box.
# 2. Copy the JSON output below this cell into the `mycreds_file_contents`
#    variable.  Authentication will occur automatically from now on.
# 3. Create a new folder in Google Drive and copy the ID of this folder
#    from the URL bar to the `folder_id` variable.
# 4. Specify the directory to be backed up in `dir_to_backup`.

Event Loop

In computer science, the event loop, message dispatcher, message loop, message pump, or run loop is a programming construct that waits for and dispatches events or messages in a program.

It works by making a request to some internal or external "event provider" (that generally blocks the request until an event has arrived), and then it calls the relevant event handler ("dispatches the event").

The event-loop may be used in conjunction with a reactor, if the event provider follows the file interface, which can be selected or 'polled' (the Unix system call, not actual polling).

The event loop almost always operates asynchronously with the message originator.

A minimal HTTP server in python. It sends a JSON Hello World for GET requests, and echoes back JSON for POST requests.
