Python保存文件

Question

I am trying to write and save a file but the following error is raised by the python script:

OSError: [Errno 22] Invalid argument: 'C:/Export/ixxxx/izzzzz_2015-05-12 17:00:00.shp

What is wrong with the path? The directory exists.

Answer 1

You aren't allowed to use colons in file names in Windows (which I'm guessing is what you're using given the rest of the path). There is a bit more information here .

Answer 2

In Windows, you can have a colon immediately after the volume name ( C: ), but not anywhere else in the path. You'll need to replace the colons with another character. I would use the - character, to keep it consistent with your date format. As a matter of personal preference, I would probably also replace the space in the filename with a - .

See the following example:

>>> pathname = 'C:/Temp'  # Change this to your pathname.
>>> filename = 'izzzzz_2015-05-12 17:00:00.shp'
>>> filename = filename.replace(':', '-').replace(' ', '-')
>>> print('{}/{}'.format(pathname, filename))
C:/Temp/izzzzz_2015-05-12-17-00-00.shp
>>> with open('{}/{}'.format(pathname, filename), 'w') as f:
...     pass
...
>>>
