def countfiles(pathname):
    result=0
    for filename in os.listdir(pathname):
        fullname=os.path.join(pathname,filename)
        if os.path.isdir(fullname):
            result+=countfiles(fullname)
        elif os.path.isfile(fullname):
            result+=1
    return result
pathname=raw_input("请输入文件路径:")
filecount=countfiles(pathname)
print("文件总数:{0:d}".format(filecount))
