Python之查找某目录中最新的文件

记录一下这个方法，感觉很有用！>.<

import os
def find_newest_file(path_file):
    lists = os.listdir(path_file)
    lists.sort(key=lambda fn: os.path.getmtime(path_file +'\\'+fn))
    print(lists)
    file_newest = os.path.join(path_file,lists[-1])
    return file_newest
if __name__ =='__main__':
    file_newest = find_newest_file(r'D:\pythoncode\login_test\report')
    print(file_newest)
