# Pls Help! where's the mistake !? - MEDIAN

#1

It gives the error that "median[4,5,5,4] returned 4 instead of 4.5"

I don't see any mistake in my code so what's the reason for this error ??

``````Replace this line with your code.

def median(raw_data):
data = sorted(raw_data)
countdown = 0
for i in data:
countdown += 1
return countdown
if countdown % 2 == 0:
num1 = (countdown / 2) - 1
num2 = num1 + 1
inter = data[num1] + data[num2]
final = float(inter / 2)
return final
else:
num = ((countdown + 1) / 2) - 1
return data[num]``````

#2

a function ends, the moment a return keyword is reached, which in your case is happen rather quickly:

``return countdown``

i recommend to remove it, since it doesn't seem to serve a purpose.

Then there is a problem here:

``final = float(inter / 2)``

float will cast the result of inter/2 (in case of the error 9 / 2 which is 4) into a float, which becomes 4.0

You might want to use float slightly differently, if you need more help let me know

Thanks!! Now it works
