__import__() protocol implementation

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

python
# __import__() - implementing the protocol
class Custom:
    def ____import____(self):
        return "custom result"

obj = Custom()
print(__import__(obj))

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

Edge cases with __import__()

Handling unusual inputs and edge cases.

python
# __import__() edge cases
print("Edge case handling for __import__()")

# Type checking
print(type(42))

Knowing these edge cases prevents subtle bugs in production.
