what is the python coding for this problem:

Write a program, using Object-Oriented Programming, to compute a taxi fare. In some cities, taxi fares are calculated based on start and end zones plus a per-minute charge. In this city, there are three zones (1, 2, and 3) and a graduated scale for time. The program should have a function that computes the taxi fare. The function should receive three parameters: the starting zone, the ending zone, and the time of the ride. It should return the total fare for the ride. Use the following table for your calculations:

Start zone	End zone	Base charge
1	1	$5.00
1	2	$7.00
1	3	$8.00
2	1	$7.00
2	2	$5.00
2	3	$9.00
3	1	$8.00
3	2	$9.00
3	3	$5.00

Time is more than	But is not over	Charge
0 minutes	4 minutes	$0.75 per minute
4 minutes	10 minutes	$3.00 plus $0.50 per minute over 4 minutes
10 minutes	20 minutes	$6.00 plus $0.40 per minute over 10 minutes
20 minutes	No limit	$10.00 plus $0.30 per minute over 20 minutes
