The third way to check if two sets are equal is by using issubset(). This function returns True only if one set is a subset of another?that is, it contains all elements of the other set. Finally, you can use the symmetric_difference() function to determine if two sets are equal. ...
要找到$I文件,我们在tsk_util实例上调用recurse_files()方法,指定要查找的文件名模式,开始搜索的path和用于查找文件名的字符串logic。logic关键字参数接受以下值,这些值对应于字符串操作:startswith,endswith,contains和equals。这些指定了用于在扫描的文件和文件夹名称中搜索我们的$I模式的字符串操作。
我们经常做单元测试使用的机制 if __name__ == '__main__' ,表明作为主程序运行的Python 源文件可以被视为名为 __main__ 的 module,当然以 import py 方式加载,则__name__ 不会为 __main__。在初始化 __main__ module 时会将('__builtins__', __builtin__ module)插入到其 dict 中。也就...
