"""Solution 10.10.3 — Lambda with map

Chapter 10: Functions — Everyday Programming

Bug type: Logical

The lambda adds 2 instead of doubling, so 1 becomes 3, not 2. Multiply
by 2 to double each number.

Exercise: ex_10_10_3.py
"""

numbers = [1, 2, 3]
doubled = list(map(lambda n: n * 2, numbers))
print(doubled)  # [2, 4, 6]
