I'm working on a Python class that has an attribute called 'number'. Currently, if I want to compare two objects, I have to write something like obj1.number > obj2.number. However, it's getting a bit tedious to keep typing '.number'. Is there a way to redefine the comparison so that I can just use obj1 > obj2 instead?

You can absolutely redefine comparison operators in Python using magic methods like __eq__, __lt__, and __gt__. For example, you might set it up like this:
```python
class MyClass:
def __init__(self, number):
self.number = number
def __eq__(self, other):
return self.number == other.number
def __lt__(self, other):
return self.number other.number
```
With this structure, you can use >, <, == directly between instances of your class!
Just to add to this, what you're doing is called 'operator overloading', and those methods with double underscores are often called 'dunder' methods!
