Let's say you overwrite the `__mul__` operator in a class in Python, but you don't want the function to be called for all kinds of input. You can specify the type by just returning `NotImplemented` for types you don't want.
|
|
|
|
```python
|
|
class A:
|
|
def __mul__(self, x):
|
|
if not isinstance(x, A):
|
|
return NotImplemented
|
|
return someOperation()
|
|
```
