作为得第一反应，就是想的直接遍历统计或者转换成字符串，调用count()


# -*- coding:utf-8 -*-
class Solution:
    def GetNumberOfK(self, data, k):
        # write code here
        res = 0
        for i in data:
            if i == k:
                res += 1
        return res

or

# -*- coding:utf-8-*-
classSolution:
    def GetNumberOfK(self, data, k):
        # write code here
        s = ""
        fori in data:
            s = s + str(i)
        returns.count(str(k))
