Python is a high-level, interpreted programming language known for its simplicity, readability, and versatility. It supports multiple programming paradigms—such as object-oriented, procedural, and functional programming—and is widely used for web development, data analysis, machine learning, automation, scripting, and more.
🔹 Key Features of Python:
Easy-to-read syntax (similar to plain English)
Dynamically typed (no need to declare variable types)
Large standard library and active community
Cross-platform support (Windows, macOS, Linux)
Extensive support for third-party packages (via PyPI)

a, b = 5, 10
a, b = b, a
Count vowels in a string.
s = "interview"
vowels = 'aeiou'
count = sum(1 for char in s if char in vowels)
