用BeagleBone在黑屏上创建文件夹

Question

我用Pyhton(2.7)中的代码在beagle bone black上创建文件夹，我将数据复制到这些文件夹中。这些文件夹安装在micro-SD卡(存档)和拇指驱动器(实时数据拷贝)上。这个文件是在我的工作目录中创建的。

代码：

@staticmethod  # Creates a folder if not present
def create_folder(folder_name):
    directory = os.path.dirname(folder_name)
    try:
        os.path.exists(directory)
        print("Folder failed")
    except:
        os.makedirs(directory, 0o777)
        print("Folder created")

错误：

Traceback (most recent call last):
  File "/var/lib/cloud9/TEMS_Operations/System_Files.py", line 125, in <module>
    temp.create_folder(temp.main_folder)
  File "/var/lib/cloud9/TEMS_Operations/System_Files.py", line 41, in create_folder
    directory = os.path.dirname(folder_name)
  File "/usr/lib/python2.7/posixpath.py", line 122, in dirname
    i = p.rfind('/') + 1
AttributeError: 'function' object has no attribute 'rfind'

有什么建议吗？

测试程序：

def test(self):                 # System file test
    name1 = self.alarm_file()
    print(name1)
    name2 = self.data_file()
    print(name2)
    name3 = self.main_folder()
    print(name3)
    name4 = self.arch_folder()
    print(name4)

    self.create_data_file(name2)
    self.create_alarm_file(name1)
    self.create_folder(name3)
    self.create_folder(name4)

    file_to = name3 + name1
    file_from = mane4 +name1

    self.copyfile(file_from, file_to)


temp = SystemFiles("ZapOFS", "ZapLab")
print(os.getcwd())
temp.test()

错误：

    /media/usb/2019/1

允许在python中创建文件夹的唯一方法是删除当前用户的sudo密码，并为程序添加-rw权限。

# sudo echo "debian  ALL=NOPASSWD: ALL" >>/etc/sudoers

不是我想要的，但我能找到的唯一方法。
