Who can explain this question ??

Question

for loops allow you to easily iterate through lists.

Given a list of numbers, output their sum.

Sample Input
1 3 7 5

Sample Output
16

What is missing that did not write:

Answer 1

The "sum = 0" should be outside the for loop so every iteration, the value won't reset to 0.

Same with "print(sum)", because based on the desired output, you only need to print the sum, not the cumulative sum (total every iteration).

And by the way, if you want to get the input of for example 1 3 7 5:
inpt = [int(x) for x in input().split()]

split() splits the string(default input type) by whitespaces by default and so the 1 3 5 7 will become ["1", "3", "5", "7"] but each element is still a string so to make each element an integer, use list comprehension, [int(x) for x in list]

Some additional useful function:
>> print(sum(list))
>> # this will print the sum of each element of a tuple, list, etc. without using "for loop".

I hope this helps.

Yes that was nice and smooth explanation Thank you for your help

Answer 3

x = [42, 8, 7, 1, 0, 124, 8897, 555, 3, 67, 99]

sum = 0
for x in x:
sum += x
print(sum)
