💻 Code Examples Overview

Example: Calculate Fibonacci Sequence

# Beginner: Using a loop
def fibonacci_loop(n):
    result = []
    a, b = 0, 1
    for _ in range(n):
        result.append(a)
        a, b = b, a + b
    return result

# Intermediate: Using generator (memory efficient)
def fibonacci_generator(n):
    a, b = 0, 1
    for _ in range(n):
        yield a
        a, b = b, a + b

# Advanced: Using async generator
async def fibonacci_async(n):
    a, b = 0, 1
    for _ in range(n):
        await asyncio.sleep(0)  # Allow other tasks
        yield a
        a, b = b, a + b

Example: Data Processing

# Beginner: Traditional loop
data = [1, 2, 3, 4, 5]
squared = []
for num in data:
    squared.append(num ** 2)

# Intermediate: List comprehension
squared = [num ** 2 for num in data]

# Advanced: Functional approach
from functools import reduce
squared = list(map(lambda x: x ** 2, data))
total = reduce(lambda x, y: x + y, squared)
