Question

1. Define a function in python that returns the sum of the following 4 lists. Remember to store and re- use your code instead of summing the values for each list 4 times. Hence, define a function that takes as an argument a list and returns the sum of values.

• Copy the following lists and paste them in a Python file after you define the sum_of_values function

• Call the function and pass to it a different list each call as an argument

  list1 = [5, 7, 4, 1, 8, 9, 56, 34, 65, 100]
  list2 = [1, 2, 5, 6, 8, 6, 0, 19, 8, 10, 11, 12]
  list3 = [1.1, 1.6, 7.8, 9.4, 6.7, 8.9, 99.7, 65.6, 45.5, 54.5, 12.7] list4 = [10.5, 100.5, 20.5]

Answer 1

Here is code:

def sum_of_values(list):
sum = 0
for val in list:
sum = sum + val
return round(sum,1) # round value

list1 = [5, 7, 4, 1, 8, 9, 56, 34, 65, 100]
list2 = [1, 2, 5, 6, 8, 6, 0, 19, 8, 10, 11, 12]
list3 = [1.1, 1.6, 7.8, 9.4, 6.7, 8.9, 99.7, 65.6, 45.5, 54.5, 12.7]
list4 = [10.5, 100.5, 20.5]

print("The sum of list1 is : ", sum_of_values(list1))
print("The sum of list2 is : ", sum_of_values(list2))
print("The sum of list3 is : ", sum_of_values(list3))
print("The sum of list4 is : ", sum_of_values(list4))

Output:
