create new variable that sums the array

[prasanthbab1234]

Hi Folks,

Could you please help me to understand how to create new variable that sums the array

create another variable that sums the array arg_numbers. Finish the line that starts with numbs_sum = by calculating the sum of all of numbers in the argument.

1. numbers = [13, 5102, 45, 2301.40, 203, 1502, 3]

numbers_sum = sum(numbers)
if len(numbers) >= 1:
    print(numbers_sum/len(numbers))
else:
    print(0)

If this is your data:

numbers = [13, 5102, 45, 2301.40, 203, 1502, 3]

You call the function sum, which returns the sum and assign it to a name.

total = sum(numbers)

total is now the sum of numbers.
I can be a float, but in your case it's an int because all input values are integers.

Then you can print the value:

print("Sum of number is:", total)

Hi Da Bishop,

Thanks for your prompt response the real query as below.

numbers = [13, 5102, 45, 2301.40, 203, 1502, 3]
numbers_sum = sum(numbers)
if len(numbers) >= 1:
    print(numbers_sum/len(numbers))
else:
    print(0)
# Complete the mean function 
[python]def mean(_____):
    numbs_sum = ______
    if ________:
        return _______
    else:
        return _______ 
# Test code - Do not change anything below this line
print(mean(numbers))
 

step 1:-
Fill in the blank in the mean function by providing the argument, which we will call - arg_numbers.

def mean(arg_numbers):

step2 :-
Now let's create another variable that sums the array arg_numbers. Finish the line that starts with numbs_sum = by calculating the sum of all of numbers in the argument.

numbs_sum = ______

so I struck in this step 2 level.

Line 2 does that
