$0.04

应该是不写东西不符合Python的语法。
在 if True: 的后面要写做出选择后要做的事情，什么都不做写个pass，像这样：

``` python
if True：
    pass
```

如果加了pass为什么再加其他的语句还是会被运行？pass的作用是？

你是说这样的情况吗？pass不是跳过某段程序的意思
pass 是用来占位子的，为了让写的程序符合语法，就像上面那样

我知道的pass有两个作用：
一是像上面那样，什么都不做；
另一个是，还没想好程序的某个功能怎么写，写个pass占位子，以后有思路了再完善程序。

哦，理解了，我以为是整个if内的都pass，看来是我理解错了！多谢！
