Of course it does. Each time you go through the loop, you change the
value of "something" to the new value.
If you do this:
x = 23
x = 42
print(x)
What do you expect to print? Hopefully 42.
If you want multiple values, you need something like a list:
x = []
x.append(23)
x.append(42)
print(x)
Of course, in *this* case, there is an easier way to create a list with
two values:
x = [23, 42]
but in the general case where you don't know how many values you will
have, you need to add them using append inside a loop.
