Python3 代码解答如下:

class Solution:
    def divide(self, dividend, divisor):
        """
        :type dividend: int
        :type divisor: int
        :rtype: int
        """
        a = dividend // divisor
        if a < -2**31 or a > 2**31-1:
            return 2**31-1
        elif a < 0:
            return - (abs(dividend) // abs(divisor))
        else:
            return a
