python intro

Sure, here’s a cheat sheet for Lesson 1: Introduction to Python:

Basics:

• Python: High-level, interpreted programming language known for its simplicity and readability.
• Jupyter Notebook: Interactive environment for running Python code.

Syntax:

• Variables: Containers for storing data. Example: x = 5
• Data Types:
  • Integer: int, Example: 5
  • Float: float, Example: 5.0
  • String: str, Example: 'hello'
  • Boolean: bool, Example: True
• Arithmetic Operators:
  • Addition: +
  • Subtraction: -
  • Multiplication: *
  • Division: /
  • Exponentiation: **
  • Modulus: %
• Printing: Displaying outputs. Example: print("Hello, world!")

Example Code:

# Variables
x = 5
y = 3.14
name = "Alice"
is_valid = True

# Arithmetic Operations
result = x + y
print("Result:", result)

# Printing
print("My name is", name)

Notes:

• Python is dynamically typed, meaning you don’t need to declare variable types explicitly.
• Use # for comments.
• Python uses indentation for code blocks instead of braces {} like in other languages.
