Are you new to programming and looking to dive into the world of Python? Look no further! In this beginner-friendly tutorial, we’ll take you through the fundamentals of Python programming, starting from data types all the way to classes. Let’s get started!

1. Data Types in Python:

Python supports various data types to represent different kinds of information. Here are some commonly used data types:

  • Integer: Whole numbers without any decimal points.
  • Float: Numbers with decimal points.
  • String: A sequence of characters enclosed within single or double quotes.
  • Boolean: Represents the truth value of an expression (True or False).
# Examples of data types in Python
my_integer = 10
my_float = 3.14
my_string = "Hello, Python!"
my_boolean = True

print(my_integer, type(my_integer))
print(my_float, type(my_float))
print(my_string, type(my_string))
print(my_boolean, type(my_boolean))

2. Functions and Methods:

Functions and methods are reusable blocks of code that perform specific tasks. Functions are defined using the def keyword, while methods are functions that belong to objects.

# Example of defining a function
def greet(name):
    print("Hello,", name)

# Example of using a function
greet("Python")

# Example of defining a method within a class
class MyClass:
    def say_hello(self):
        print("Hello from MyClass!")

# Example of using a method
obj = MyClass()
obj.say_hello()

3. Introduction to Classes:

Classes are blueprints for creating objects in Python. They encapsulate data and behavior within a single unit and enable code reusability and modularity.

# Example of defining a class
class Car:
    def __init__(self, brand, model):
        self.brand = brand
        self.model = model

    def display_info(self):
        print("Brand:", self.brand)
        print("Model:", self.model)

# Example of creating objects from a class
car1 = Car("Toyota", "Corolla")
car2 = Car("Honda", "Civic")

# Example of accessing class attributes and methods
car1.display_info()
car2.display_info()
