    class Solution:
    # @param    A       a list of integers
    # @param    elem    an integer, value need to be removed
    # @return an integer
    def removeElement(self, A, elem):
        i = 0
        for j in range(len(A)):
            if A[j] != elem:
                A[i] = A[j]
                i += 1

    It depends the test cases.
    I test your code, but the run time is 63ms.
    If the account of elem in A is large, your code is effective.
