Median of Two Sorted Array

class Solution(object):    def findMedianSortedArrays(self, list1, list2):        merged_array = list1 + list2        merged_array.sort()        length = len(merged_array)        medians = length%2        median = length/2        if medians!=0:            median = int(median)            calculation = merged_array[median]             return calculation        else:            median = int(median)            first = merged_array[median]            second = merged_array[median-1]            calculation = (second+first)            calculation = calculation/2.0            return calculation
