+In programming, especially in object-oriented programming (OOP), **methods** and **attributes** are foundational concepts that define the behavior and characteristics of objects in a class. Here's a breakdown of each:
+
+### 1. **Attributes**
+
+- **Definition**: Attributes are variables that hold data related to an object. They define the characteristics or properties of the object.
+- **Example**: Imagine a `Car` class. Attributes for a car might include `color`, `brand`, `year`, etc.
+
+#### Code Example
+
+```python
+class Car:
+    def __init__(self, color, brand, year):
+        self.color = color  # Attribute
+        self.brand = brand  # Attribute
+        self.year = year    # Attribute
+
+# Creating an object of Car class
+my_car = Car("Red", "Toyota", 2020)
+
+# Accessing attributes
+print(my_car.color)  # Output: Red
+print(my_car.brand)  # Output: Toyota
+print(my_car.year)   # Output: 2020
+```
+
+Here, `color`, `brand`, and `year` are attributes of the `Car` object. Each instance of `Car` can have different values for these attributes.
+
+### 2. **Methods**
+
+- **Definition**: Methods are functions defined within a class that perform actions using the object’s data or manipulate the object’s state. They define the behavior of an object.
+- **Example**: In the `Car` class, methods might include `start()`, `stop()`, or `accelerate()` to perform specific actions.
+
+#### Code Example
+
+```python
+class Car:
+    def __init__(self, color, brand, year):
+        self.color = color
+        self.brand = brand
+        self.year = year
+
+    def start(self):  # Method
+        print(f"The {self.color} {self.brand} car is starting.")
+
+    def stop(self):   # Method
+        print(f"The {self.color} {self.brand} car is stopping.")
+
+# Creating an object of Car class
+my_car = Car("Red", "Toyota", 2020)
+
+# Calling methods
+my_car.start()  # Output: The Red Toyota car is starting.
+my_car.stop()   # Output: The Red Toyota car is stopping.
+```
+
+In this example, `start` and `stop` are methods that describe behaviors of the `Car` object.
+
+### Key Differences
+
+- **Attributes** represent **data** about the object, while **methods** represent **actions** or **behaviors** that the object can perform.
+- Attributes are often variables, while methods are functions defined within the class.
+
+### Summary Table
+
+| **Concept**  | **Purpose**                         | **Example** in Code             |
+|--------------|-------------------------------------|----------------------------------|
+| **Attribute** | Holds data about the object       | `self.color`, `self.year`       |
+| **Method**   | Performs an action or behavior     | `start()`, `stop()`             |
+
+By defining both attributes and methods, classes create a blueprint for objects that combine state and behavior, helping to model real-world entities in a program.
