Partial Upload With storbinary in python

Question

I've written some python code to download an image using

urllib.urlopen().read()

and then upload it to an FTP site using

ftplib.FTP().storbinary()

but I'm having a problem. Sometimes the image file is only partially uploaded, so I get images with the bottom 20% or so cut off. I've checked the locally downloaded version and I have successfully downloaded the entire image, which leads me to believe that it is a problem with storbinary. I believe I am opening and closing all of the files correctly. Does anyone have any clues as to why I'm getting a partial upload with storbinary?

Update: When I run through the commands in the Python shell, the upload completes successfully, I don't know why it would be different from when run as a script...

Answer 1

It turns out I was not closing the downloaded file correctly. Let's all pretend this never happened.
