Need a reminder to notify colleague so that he/she will not miss the train.
A schedule alert will pop-up alert message on the desktop when it's time to leave.
Python 3.6.2
The first idea is to create a script to get current coordinate then obtain arrive time and destination from user. With APIs from VBB allows getting the information of the best route. A pop-up message remains user to leave the office. But when I tried to get current coordinate, the responded coordinate always near Berliner Dom so that I changed the way to create a simple alert script. Which only need to enter a expect leave time. Then problem solved.
