问题描述
我正在尝试检测带有扩展名列表的文件.
I'm trying to detect files with a list of extensions.
ext = [".3g2", ".3gp", ".asf", ".asx", ".avi", ".flv", \ ".m2ts", ".mkv", ".mov", ".mp4", ".mpg", ".mpeg", \ ".rm", ".swf", ".vob", ".wmv"] if file.endswith(ext): # how to use the list ? command 1 elif file.endswith(""): # it should be a folder command 2 elif file.endswith(".other"): # not a video, not a folder command 3推荐答案
为此使用元组.
>>> ext = [".3g2", ".3gp", ".asf", ".asx", ".avi", ".flv", \ ".m2ts", ".mkv", ".mov", ".mp4", ".mpg", ".mpeg", \ ".rm", ".swf", ".vob", ".wmv"] >>> ".wmv".endswith(tuple(ext)) True >>> ".rand".endswith(tuple(ext)) False与其每次都进行转换,不如将其转换为元组一次.
Instead of converting everytime, just convert it to tuple once.
