Python Built-in Modules 📦

Standard Library

Python comes with a "batteries included" philosophy, meaning it includes a rich standard library of modules for common tasks.

✨ Essential Modules

Math & Numbers

  • math - Mathematical functions
  • random - Generate pseudo-random numbers
  • decimal - Decimal fixed point and floating point arithmetic

File & System

  • os - Operating system interfaces
  • sys - System-specific parameters and functions
  • pathlib - Object-oriented filesystem paths

🚀 Example: Random Module

python
import random

print(random.randint(1, 10))  # Random integer between 1 and 10
print(random.choice(['apple', 'banana', 'cherry']))  # Random choice
