Question

Which of the following will give you a sum of numbers equal to 15

	1.	s = 0 for i in [9,5,1]:     s = s + i
	2.	All of the above.
	3.	sum(list((9,5,1)))
	4.	None of the above.
	5.	s = 0 for i in [9,5,1]:     s += i

Answer 1

If we want to iterate over a sequence like a list, a tuple, a dictionary, a set or a

The for keyword used like other programming languages.

We can execute a set of statements, once for each item in a list, tuple, set etc. using the for loop.

Syntax of for Loop

for val in sequence:

          Body of for

Option 1: Correct

s = 0 // initialization of sum variable
for i in [9, 5, 1]:// iterate over a list one by one
    s = s + I // add value into variable s which is sum of number.

Option 3: Correct

The sum () function returns the sum by adding the items of an iterable ((list, tuple, dict, etc). The items of the iterable should be numbers.

Option 5: Correct

The expression s += i is shorthand for s = s + i.So code is similar to option 1

Thus Answer is

2.	All of the above.
