Get current real-time travel time using Python and Google's distance matrix

Get_current_real-time_travel_time.py

#!/usr/bin/python

# This script wil get the real-time travel time between your home and your work (in both directions at the current time).
# 
# You could use this script to map the real time travel times of the past day (cron job, every minute)
# To plot grpahs you could use: http://plot.ly
#
#
# If you want to plat the estimated driving times for each minute of a given day in the future, check out my gist:
# Get estimated travel times using Python and Google's distance matrix

# To get cooordinates -> Google maps -> right-click -> What's here -> coordinates see bottom of card

How to fix that in other version program?

This is due to the list being empty i.e with the API keys being invalid , Your request was denied.
Try to procure an API key from Google Develop Project and substitute the values for API1 & API2.

I have a problem, can some help me out?

I have a question,
I have coords in a CSV file, How can I read through it instead of a single coord?

Thanks
