1、这段代码执行过程是怎样的，2、IsFind在里面有什么用，麻烦帮忙解释下，多谢了

零星琐碎

name = input('请输入待查找的用户名：')
score = [['迷途', 85], ['黑夜', 80], ['小布丁', 65], ['福禄娃娃', 95], ['怡静', 90]]
IsFind = False

for each in score:
    if name in each:
        print(name + '的得分是：', each[1])
        IsFind = True
        break
   
if IsFind == False:
    print('查找的数据不存在！')

isfind是一个标识，这个标识是为了判断是找到了跳出循环结束程序，还是循环完没找到，程序才结束！
如果是因为跳出循环结束程序，那么isfind的bool为1.  否则为0.

试了一下，程序跑后，你可以在终端查看isfind的值，从而可以得知究竟为何结束程序。好巧妙的办法！
