Your program should look like this with proper indentation.

def func(x):
res = 0

for i in range(x):
res += i
return res

print(func(4))

--------

Explanation: we have defined a function and passed 4 as a parameter.

Now in that function we have loop with range (x)

for x = 4, range (4) will return list [0, 1, 2, 3]

And we are adding this list values using loop so here output is 0 + 1 + 2 + 3 = 6

Answer 2

Your indentation in improper. Better write the code in code playground and share its link here.
