Introduction to Python

What is Python?

Python is a high-level, interpreted programming language known for its clean syntax and readability. It was created by Guido van Rossum and first released in 1991.

Unlike compiled languages such as C or Java, Python code is executed line by line by an interpreter, which makes it great for rapid development and prototyping.

Python emphasizes code readability and uses indentation (whitespace) to define code blocks instead of curly braces, making it one of the easiest languages to learn.

• High-level: Python handles memory management and low-level operations automatically
• Interpreted: Code runs directly without needing to be compiled first
• Dynamically typed: You don't have to declare variable types — Python figures them out at runtime
• Multi-paradigm: Supports procedural, object-oriented, and functional programming

# Your very first Python program
print("Hello, World!")

# Python is known for being concise
name = "Priodemy"
print(f"Welcome to {name}!")

# Your very first Python program
print("Hello, World!")

# Try changing the name below
name = "Priodemy"
print(f"Welcome to {name}!")

Why Learn Python?

Python consistently ranks as one of the most popular programming languages in the world. Its versatility means you can use it for almost anything — from web development to artificial intelligence.

Python has a massive ecosystem of libraries and frameworks, and a welcoming community that makes it easy to find help and resources.
