I have this little program that is supposed to calculate how many diagonals
a polygon of x sides has, but it does not return what I have in the
"return" part of the function when I call it. Here is the code:
def num_diag(var):
ans = 0
if var <= 3:
print("No diagonals.")
else:
for i in range(num_sides - 3):
ans = ans + i
return (((var - 3)*2) + ans)
num_sides = (int(raw_input("Enter sides: ")))
num_diag(num_sides)
Any suggestions as to what is going on? When I run it, it prompts me for
the number of sides, and that's it.
Thanks.
