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.
