Example of Abstraction in Python

Abstract classes are classes that contain one or more abstract methods. An abstract method is a method that is declared, but contains no implementation. Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods. 

Bangalore to kempegowda international airport

Hi, Myself anil, I want to tell  you those incident which lead to me create a app names AirPortBus for Bangalore

Incident - 01

When I came to Bangalore via Flight then I found that it is to far away from my destination. Every Radio taxi or other cab services charge upto Rs 800 - 1000. This cost is too much for me as I came here for job search so I cannot afford this too much fare, then I called to my friend who is already stay here for many years he told me that there is also AirportBus service which charge less amount upto 300 Rs depends on destination in Bangalore. This is first time when it come to know that here also airport bus service is available.

Incident - 02

I want to go to my home in Delhi on the occasion of  Holi festival (North India famous festival). Again I booked my ticket for flight to Delhi. The flight time was in the evening 8:00 pm. I check bus timing which is appropriate for me to reach airport on time, I found that a bus of time 5:00 pm is good for me. I went to my bus stop at 4:00 pm and waiting for bus. My watch show time 5:00 pm but there is no bus. I thought that may be there is traffic jam so I should wait. Since that moment there is no internet in my phone so that I can check another bus there is also a problem that I do not know my nearby stops where other airport bus pass so,  I wait at bus stand till 6:00 pm but there is no bus. Now only two hours left to reach airport. I left hope to reach to airport on time but I gave myself a chance. I hire a auto and he handover to me a airport taxi. I reached on airport just 45 min ago from my flight.

These two incident force to think about to solve this problem. So I came up with an idea so that you can easily checkout buses and bus timing without availability of internet. And told my friend who lived in Delhi. He also suggest some feature to add in this app like from your current position you can check which bus stop is near to you.

We release this app in month of august with following feature which took 2 month to complete

1. Show all Airport Buses
2. Show all stops from where these buses passes
3. This app tell you each bus timing from destination and origin of bus
4. Main feature of this app is it tell you your nearby bus stop according to your current location (At moment we are not showing actual driving distance instead we are showing straight line distance from your current location to nearby stops. In upcoming upadate we try to show driving distance)
