请问“as if they were Python code”这句话（在回答 Input 和 raw_input 的区别时）该怎么理解？

What's the difference between input() and raw_input()?
The input() function will try to convert things you enter as if they were Python code, but it has security problems so you should avoid it.

在 python2 中 input 会把读到的 python 代码跑起来

一个是输入纯字符串所以是 raw ，一个是输入表达式所以有安全隐患。另外笨办法学 python 应该有中文翻译版本的吧

input 会假设用户输入的是合法的 Python 表达式而 raw_input 会把输入的内容当作原始数据一般情况下多用 raw_input

as if 连词＝ like （口语习惯）

'like/as if/as though' is used to say how somebody or something looks/sounds/feels.
'as if' and 'as though' are more formal than 'like'.

After 'as if'(or 'as though'), we sometimes use the past when we are talking about the present.
for example:
'as if they were Python code'
The meaning is not past in this sentence, We use the past('were') because the things you enter for the function input() is not really Python code, it will be converted and run.
