Python Tip of the Day: Functional Programming with map(), filter(), and reduce()

# Using map, filter, and reduce
from functools import reduce

numbers = [1, 2, 3, 4, 5]

# Double each number
doubled = list(map(lambda x: x * 2, numbers))
print(doubled)  # Output: [2, 4, 6, 8, 10]

# Filter out even numbers
evens = list(filter(lambda x: x % 2 == 0, numbers))
print(evens)  # Output: [2, 4]

# Sum all numbers
total = reduce(lambda x, y: x + y, numbers)
print(total)  # Output: 15
