引发AssertionError与断言python [英] raise Assertionerror vs. assert python

问题描述

引发Assertionerror和断言以建立故障"之间的最大区别是什么.对代码有什么影响?并且在某种程度上，另一个或另一个是pythonic吗?

What are the big differences between raise Assertionerror and assert to build in a "fault". What are the effects on the code ? and is one or the other more pythonic in a way ?

我提出这个问题的原因是因为我正在学习编程，现在我们进行了练习，例如，当x！="ok"(x是某个数字)时，我们需要获取AssertionError"false".

The reason for my question is because I am learning to program right now we have exercise where for example when x != "ok" (x be a certain number) we need to get an AssertionError "false".

我在网上查找了此内容，然后他们说要设置以下代码:

I looked this up online and then they say to set the following code:

if x != 0:
    raise AssertionError ("false")

但是我的老师也经常使用以下内容

but my teachers also use the following a lot

assert x == "ok","fout"

此方法的(缺点)有哪些优点?

What are the (dis)advantages to this approach ?

已经非常感谢

推荐答案

这两个代码示例是等效的，但可以使用-O命令行标志全局禁用assert语句.

Those two code examples are equivalent, with the exception that assert statements can be globally disabled with the -O command-line flag.
