os.walk()的作用

#os.walk()的作用就是遍历指定目录下的所有文件
import os
def fileDir():
    fileDir = "E:" + os.sep + "学习程序"
    for i in os.walk(fileDir):
        print(i[0])
        print(i[1])
        print(i[2])

    os.system("")          #os.system的返回值是脚本的退出状态码，只会有0(成功),1,2
if __name__ == "__main__":
    fileDir()
    print(type(fileDir()))
