这可能是最简单的例子:当late被传递给if语句时,late充当条件表达式,在布尔上下文中进行评估(就像我们调用bool(late)一样)。如果评估的结果是True,那么我们就进入if语句后面的代码体。请注意,print指令是缩进的:这意味着它属于由if子句定义的作用域。执行这段代码会产生: ...
In summary, os.path.join() is a very convenient tool to construct filepaths. Why do we need to use it? Two reasons: (1) It takes care of adding the file separator itself. So even if you forget, Python doesn’t. (2) Even though you can achieve the result by string concatenation,...
