1、msg如果条件(to_check%2==0)为,则将被分配为“偶数”true;2、msg如果条件(to__check%2==0)为,则将被分配为“奇数"false。 问题20:Python中的全局变量和局部变量是什么? 全局变量:在函数外部或全局空间中声明的变量称为全局变量。程序中的任何函数都可以访问这些变量。 局部变量:在函数内部声明的任何变量...
You can simply check if the List is empty with: ifnotmy_list:print("List is empty") This is using theTruth Value Testingin Python, also known as implicit booleaness or truthy/falsy value testing. Among other rules it defines that empty sequences and collections like'', (), [], {},...

输出结果为:“a is empty”。这是因为math.isnan()函数判断a的值是否为NaN,如果是,则被判断为空。 代码示例 下面是一个完整的代码示例,演示了如何判断float是否为空,并根据判断结果进行相应的处理: importmathdefcheck_float(value):ifvalue==value:print("The float value is not empty")else:print("The ...
Then run pytest tests to check the test result.Temporary filesThe tempfile.gettempdir() method returns a temporary folder, which on Linux is /tmp. Your application can use this directory to store temporary files that are generated and used by your functions when they're running....
