This is the code I wrote:

```
def median(numbers):
l = sorted(numbers)
count = 0
for x in l:
count += 1
while count > 2:
del l[0]
del l[count-2]
count -= 2
if count == 2:
return (l[0] + l[1]) / 2
else:
n = l[0]
return n
```

Here on codecademy I get the error: median([4, 5, 5, 4]) returned 4 instead of 4.5

But when I try this In PyCharm I get 4.5

When I try the solution in PyCharm, I get this error: TypeError: list indices must be integers or slices, not float

I have python 3.6 on my PC.

Is one of them bugged or are the different python versions to blame?
