min() — Advanced Examples

Returns the smallest item in an iterable or among arguments

min() protocol implementation

Implementing the protocol that min() uses under the hood.

python

# min() - implementing the protocol
class Custom:
    def __min__(self):
        return "custom result"

obj = Custom()
print(min(obj))

Understanding the dunder methods that min() calls helps you customize behavior for your own classes.

Handling unusual inputs and edge cases.

python

# min() edge cases
print("Edge case handling for min()")

# Type checking
print(type(42))

Knowing these edge cases prevents subtle bugs in production.
