python一些常用函数



import os

def find_current_dir():#遍历当前目录
    for root, dirs, files in os.walk("c:\\mnist", topdown=False):
        for name in files:
            print(os.path.join(root, name))
        for name in dirs:
            print(os.path.join(root, name))
   

       

def find_file(arg,dirname,files):遍历所有子目录

    for file in files:

        file_path=os.path.join(dirname,file)

        if os.path.isfile(file_path):

            print("find file:%s" %file_path)

    

 

os.walk("c:\\mnist",find_file,())
