I have two sorted arrays and I am trying to find median of two sorted arrays.**For example,if input is nums1 = [1,3], nums2 = [2] then the output will median=2.00000 and if the input is p = [1,2], t = [3,4] then the output will be median=2.50000** I have added both the arrays together and sorted them and later by using their lengths I have tried to calculate the correct value. Below is my code

class Solution(object): def findMedianSortedArrays(self, nums1, nums2): nums1.extend(nums2) nums1.sort() if len(nums1)%2 ==0: a = len(nums1)/2 return float(nums1[a]+nums1[a-1])/float(2) else: a = len(nums1) / 2 return float(nums1[a]) if __name__ == "__main__": p = [1,3] t = [2] print(Solution().findMedianSortedArrays(p,t))

Below is the error in the logs.

return float(nums1[a]) TypeError: list indices must be integers or slices, not float

## Answer

Division of integers yields a float

but you could trivially check this by printing out `a`

just before using it as an index. And the error is extremely clear that `a`

*is* a float at that point.

Either coerce it to int, as

nums1[int(a)]

or use floor division, with

a = len(nums1) // 2
