Answer 2

//The output is: 6

Trying explainations:

1- def func(x)
/*defining a function named "func" with an argument "x", i beleive u know it, dont worry!*/

2- res=0
//initialising variable "res" to 0

3- for i in range(x)
/*looking for all the first 4th int (starting from 0 to argument x entered below, with a variable "i" used to store or define the index of each of those elements*/

4- res+=i
/*while loking for those numebers, adding each time to "res" the new value of "i" the element's index*/

5- return res
//returning the final value of res at the loop end

6- print(func(4))
/*calling the "func" function with the parameter 4, that will repace "x" in the function execution, and print the returned value*/

//execution:
res=0
res=res+i (0+0)
res=res+i (0+1)
res=res+i (1+2)
res=res+i (3+3)
res==6
