本文介绍了一个简单的方法来计算一个整数的汉明重量（即二进制表示中1的个数）。通过一个Python类`Solution`及其实现的方法`hammingWeight`，我们演示了如何迭代地检查整数的每一位，并计算出1的总数。

题目：这里

我的答案

class Solution(object):
    def hammingWeight(self, n):
        """
        :type n: int
        :rtype: int
        """
        num = 0
        while n > 0:
            if n%2 != 0:
                num +=1
            n = n/2
        return num

挺简单的，注意下n的判断条件就行

确定要放弃本次机会？
