## Python Classes and Objects

Classes and objects are the two main building blocks of object-oriented programming (OOP) in Python. A class is a blueprint for creating objects, and an object is an instance of a class.

Classes define the properties and methods of objects. Properties are data attributes that belong to an object, and methods are functions that can be called on an object.

To create a class, you use the `class` keyword. The following code creates a class called `Person`:

```python
class Person:
def __init__(self, name, age):
self.name = name
self.age = age

def say_hello(self):
print("Hello, my name is {} and I am {} years old.".format(self.name, self.age))
```

To create an object of a class, you use the `()` operator. The following code creates an object of the `Person` class and assigns it to the variable `p`:

```python
p = Person("John Doe", 30)
```

You can then access the properties and methods of the object using the dot operator (``.``). For example, the following code prints the name and age of the object:

```python
print(p.name)
print(p.age)
```

You can also call the methods of the object. For example, the following code calls the `say_hello()` method of the object:

```python
p.say_hello()
```

Classes and objects are powerful tools that can be used to create complex and efficient programs. For more information on classes and objects in Python, please refer to the [Python documentation](https://docs.python.org/3/tutorial/classes.html).
