You can define methods outside of class definition. However, you need to make sure that you bound the method *to the class* itself **not** instance.

|

|
|
```python
|
||
|
|
class Foo:
|
||
|
|
x = 42
|
||
|
|
|
||
|
|
|
||
|
|
def bar(self):
|
||
|
|
return self.x
|
||
|
|
|
||
|
|
|
||
|
|
if __name__ == "__main__":
|
||
|
|
foo = Foo()
|
||
|
|
|
||
|
|
Foo.bar = bar
|
||
|
|
print(foo.bar()) # 42
|
||
|
|
|
||
|
|
foo.bar = bar
|
||
|
|
print(foo.bar()) # error, because `bar` doesn't know about `self`
|
||
|
|
```
