Function in Python that takes a list of integers as input and returns the sum of all the even numbers in the list.
# Input
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# Output
# Sum of even numbers: 2 + 4 + 6 + 8 + 10 = 30
print(sum_even_numbers(numbers)) # Output: 30
Solution:
def sum_even_numbers(numbers):
"""
Calculate the sum of all even numbers in a list.

Args:
numbers (list of int): List of integers.

Returns:
int: Sum of all even numbers in the list.
"""
return sum(num for num in numbers if num % 2 == 0)

# Test the function
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print(sum_even_numbers(numbers)) # Output: 30
