Introduction

Python is a versatile, high-level programming language that is widely used for various applications, ranging from web development to data analysis, artificial intelligence, and scientific computing. Its simplicity and readability make it a favorite among beginners and professionals alike.

The introduction of Python in programming refers to the basics of understanding the language, its features, and its syntax. Below, we will explore some key aspects of Python through examples.

1. Print Statement

The print statement is one of the simplest ways to output data in Python.

          
            # Example 1: Printing a simple message
            print("Hello, World!")

Output:

          Hello, World!

2. Variables and Data Types

In Python, you can easily assign values to variables without declaring their type explicitly.

          
            # Example 2: Working with variables
            name = "Alice"
            age = 25
            height = 5.4

            print("Name:", name)
            print("Age:", age)
            print("Height:", height)

Output:

          Name: Alice
          Age: 25
          Height: 5.4

3. Control Structures

Python includes various control structures like if-else, loops, and functions.

          
            # Example 3: Using if-else
            number = 10
            if number % 2 == 0:
                print("Even")
            else:
                print("Odd")

Output:

          Even

4. Functions

Functions in Python are defined using the def keyword.

          
            # Example 4: Defining and calling a function
            def greet(name):
                return "Hello, " + name

            print(greet("Alice"))

Output:

          Hello, Alice

5. Lists and Loops

Python provides powerful tools for working with collections, like lists and loops.

          
            # Example 5: Iterating over a list
            fruits = ["apple", "banana", "cherry"]
            for fruit in fruits:
                print(fruit)

Output:

          apple
          banana
          cherry

Conclusion

Python's simple syntax and extensive libraries make it a great choice for both beginners and experienced programmers. The examples above demonstrate some fundamental concepts that serve as the foundation for more advanced Python programming.
