Here is a Python program example to sort objects without native comparison.
Sort Objects in Python Example
The following Python program will print the sorted customer id.
from operator import attrgetter class Customer: def __init__(self, customer_id): self.customer_id = customer_id def __repr__(self): return 'customer({})'.format(self.customer_id) # Example customers = [Customer(123), Customer(13), Customer(199)] print('Unsorted customers', customers) # Sort it by customer-id print('Sorted customers', sorted(customers, key=attrgetter('customer_id')))
Output:
Unsorted customers [customer(123), customer(13), customer(199)] Sorted customers [customer(13), customer(123), customer(199)] Process finished with exit code 0
