Quick Start

# Python hello world
print("Hello, Python!")

# List comprehension
squares = [x**2 for x in range(1, 6)]
print(squares)  # [1, 4, 9, 16, 25]

# Generator (memory-efficient)
def fibonacci():
    a, b = 0, 1
    while True:
        yield a
        a, b = b, a + b

import itertools
fibs = list(itertools.islice(fibonacci(), 8))
print(fibs)  # [0, 1, 1, 2, 3, 5, 8, 13]
