The code you provided has a small mistake. The variables `o1`, `o2`, and `o3` are defined, but `obj1`, `obj2`, and `obj3` are being printed. If we correct this mistake, the output of the code will be "1 2 3".

Here's the corrected code:

```python
class A:
def __repr__(self):
return "1"

class B(A):
def __repr__(self):
return "2"

class C(B):
def __repr__(self):
return "3"

o1 = A()
o2 = B()
o3 = C()

print(o1, o2, o3)
```

This will output: `1 2 3`

This is because the `__repr__` method is used to tell Python how to represent an object of a class as a string. Each class (A, B, C) has its own `__repr__` method that returns a different string ("1", "2", "3"). When we print an object of each class, the corresponding `__repr__` method is called.
