File as variable. Is there a possibility?

[Vyiel]

Hi,
I am trying not to save a file on disk and then have it passed as an argument to donut.create().
I tried with var = open("file.exe", 'rb') and then passing var to donut.create() but it doesn't work. Is there a possibility in the future to make that work? Or it already does and I don't know it?

Thanks.
