Loops

Python loops are clean and readable. The `for` loop works great with lists and ranges.

# For loop
for i in range(5):
    print(i)  # 0, 1, 2, 3, 4

# Loop through a list
fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
    print(fruit)

# While loop
count = 0
while count < 5:
    print(count)
    count += 1

# List comprehension (powerful shortcut)
squares = [x ** 2 for x in range(10)]
