Answer:
def sum_numbers(value_list):
total = 0
for n in value_list:
if type(n) == int or type(n) == float:
total += n
return total
Explanation:
Create a function called sum_numbers that takes one parameter, value_list
Initialize the total as 0
Create a for loop that iterates through the value_list
Inside the loop, check the type of the elements. If they are either int or float, add them to total.
When the loop is done, return the total
