Pascal's Triangle II

Given an index k, return the kth row of the Pascal's triangle.

For example, given k = 3,
Return [1,3,3,1].

easy to solve

class Solution:
    # @return a list of integers
    def getRow(self, rowIndex):
        if rowIndex==0:
            return [1]
        
        result = [1]
        for rowInd in range(1,rowIndex+1):
            for elemind in range(len(result)-1,0,-1):
                result[elemind] = result[elemind] + result[elemind-1]
            result = result + [1]
            
        return result
