如何在Python中从C ++ / C＃紧密实现？ [英] How can I closely achieve ?: from C++/C# in Python?

问题描述

在C＃中，我可以轻松地编写以下内容：

In C# I could easily write the following:

string stringValue = string.IsNullOrEmpty( otherString ) ? defaultString : otherString;

在Python中是否可以快速执行相同的操作，或者我是否坚持使用'if'

Is there a quick way of doing the same thing in Python or am I stuck with an 'if' statement?

推荐答案

在Python 2.5中，有

In Python 2.5, there is

A if C else B

在C中的行为很像？：但是，它不赞成这样做有两个原因：可读性和通常有一种更简单的方法来解决问题。例如，在您的情况下：

which behaves a lot like ?: in C. However, it's frowned upon for two reasons: readability, and the fact that there's usually a simpler way to approach the problem. For instance, in your case:

stringValue = otherString or defaultString
