It’s also important to realize that error messages are a part of programming, so learning to code involves learning how to debug errors effectively. Moreover, because error messages are common, it’s usually relatively easy to figure out how to debug an error. You’re probably not the ...
上面的例子非常有趣,因为它很愚蠢。它向我们展示了两个嵌套的if子句(外部和内部)。它还向我们展示了外部if子句没有任何else,而内部if子句有。请注意,缩进是允许我们将一个子句嵌套在另一个子句中的原因。 如果alert_system == 'console',则执行#1部分,其他情况下,如果alert_system == 'email',则进入另一个if...

There are ways to get around this, but in such situations threads provide a much simpler programming model. However, as we shall see in Cython, there is a third-party package called Cython that makes it very easy to circumvent this problem with threads....
