remember when we could just print stuff without parentheses?

In Python, we often use print 🖨️ statements with parentheses to output values. However, there's a creative way to print values without using braces by leveraging properties in a custom class. Let's dive into how we can achieve this using a custom class design. 🔍

## Custom Class Design 🛠️

Here’s a simple class that allows printing values without the need for parentheses:

```python
class disp_cls():
    def __init__(self):
        return

    @property
    def out(self):
        return self

    @out.setter
    def out(self, other):
        print(other)
        return

disp = disp_cls()
disp.out = 1, 2, 3
```

### Breakdown 🧩

1. **Class Definition**: We define a class called `disp_cls`.
2. **Constructor**: The `__init__` method initializes the class but doesn't do anything special here.
3. **Property Getter**: The `out` property method returns the instance itself (`self`). This is necessary for the property to work correctly.
4. **Property Setter**: The `out` setter method is where the magic happens. It takes the value being assigned to `disp.out` (in this case, `1, 2, 3`) and prints it.
5. **Usage**: We create an instance of `disp_cls` called `disp` and assign a tuple `1, 2, 3` to `disp.out`. This triggers the setter method, which prints the tuple.

## How It Works 🚀

When we assign `disp.out = 1, 2, 3`, the following steps occur:

- The assignment triggers the `out` setter method.
- The setter method prints the assigned value (`1, 2, 3`).

This allows us to print values without explicitly calling the `print` function, thus avoiding the use of parentheses for the print statement. 🎉

## Conclusion 🏁

By using properties in a custom class, we can creatively bypass the need for parentheses when printing values in Python. This approach demonstrates the flexibility and power of Python's property decorators and can be a fun way to streamline your code. Give it a try and see how it works for you! Happy coding! 💻😊
