I did the coding, but I have error for my median. Please help.

class StatSet:

def median(self): # return median value data = self.data n = self.n data.sort() mid = n/2 if n % 2 == 0: return (data[mid] + data [mid -1] /2.0) else: return data[mid]

def main(): s = StatSet() while True: xStr = input(" Enter a number(leave blank to exit loop): ") # exit loop if xStr == "": break s.addNumber(float(xStr)) print(" Count: ",s.count()) print(" Min: ", s.min()) print(" Max: ", s.max()) print(" Mean: ",s.mean()) print(" Standard Deviation: ", s.stdDev()) print(" Median: ", s.median())
