Python Morsels Exercise

Class representing a 3-dimensional point

I'd like you to write a class representing a 3-dimensional point.

The Point class must accept 3 values on initialization (x, y, and z) and have `x`

, `y`

, and `z`

attributes.
It must also have a helpful string representation.
Additionally, point objects should be comparable to each other (two points are equal if their coordinates are the same and not equal otherwise).

Example usage:

```
>>> p1 = Point(1, 2, 3)
>>> p1
Point(x=1, y=2, z=3)
>>> p2 = Point(1, 2, 3)
>>> p1 == p2
True
>>> p2.x = 4
>>> p1 == p2
False
>>> p2
Point(x=4, y=2, z=3)
```
