【python】7. Reverse Integer

一定注意空格啥的，被折腾死了，tab不等于空格

class Solution(object):
    def reverse(self, x):
        """
        :type x: int
        :rtype: int
        """
        maxi = pow(2,31)        
        p = abs(x)
        q = abs(x)
        t = 0
        while p>0:
            t = t * 10 + p%10
            if t > maxi:
                return 0
            p = p/10
        if x == q:
            return t
        return (-1)*t
