Python USES cStringIO to implement the method of temporary memory file access

This article illustrates how python USES cStringIO for temporary memory file access. Share with you for your reference. Specific analysis is as follows:

If you want to read a file from the network for processing, but you don't want to save the file to the hard disk, you can use the cStringIO module for processing

res = urllib2.urlopen(pic,timeout=10)
f = cStringIO.StringIO(res.read())

F is a file object,
It and: f = open('c:/1.jpg','rw')   Open the same file
An in-memory file can be read and written as if it were a local file

I hope this article has helped you with your Python programming.
