Given a list of numbers, write a Python program to compute the average of all numbers.
[10, 20, 45, 60]
def compute_average(numbers):
 sum = 0
 for number in numbers:
 sum += number
 return sum/len(numbers)

numbers = [10, 20, 45, 60]
result = compute_average(numbers)
print(result)

# Output:
31.25
