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。
正则表达式模块re提供了更强大的模式匹配功能。通过re.search(pattern,string)可进行模糊匹配，支持通配符、字符集等高级特性。例如检测是否存在数字：ifre.search(r’'̣, string)。当需要复杂模式匹配时首选，但正则表达式存在编译耗时，简单匹配时效率不如in关键字。对于需要同时检测多个子串的情况，可结合列表推导式...
