Here is my code and i know there are mistakes here - `m = len(l)/2`

and here - `m = float((len(l)/2) / ((len(l)/2) - 1))`

i know i should use something instead of len(l) to use numbers instead of lengh but i can't imagine how to do this

```
def median(l):
sorted(l)
m = 0
if len(l) % 2 == 0:
m = len(l)/2
elif len(l) == 1:
m = 1
else:
m = float((len(l)/2) / ((len(l)/2) - 1))
return m
```
