Write a Python program to generate tickets for online bus booking, based on the class diagram given below.



Method description:

Initialize static variable counter to 0
validate_source_destination(): Validate source and destination. source must always be Delhi and destination can be either Mumbai, Chennai, Pune or Kolkata. If both are valid, return true. Else return false
generate_ticket():
Validate source and destination
If valid, generate ticket id and assign it to attribute, ticket_id. Ticket id should be generated with the first letter of source followed by first letter of destination and an auto-generated value starting from 01 (Ex: DM01, DP02,.. ,DK10,DC11)
Else, set ticket_id as None
Note: Perform case insensitive string comparison

For testing:

Create objects of Ticket class
Invoke generate_ticket() method on Ticket object
Display ticket id, passenger name, source, destination
In case of error/invalid data, display appropriate error message
