In Python, how do I transform a string into a file?

file, python, string, types

Solution

The `StringIO` module:

>>> import StringIO
>>> f = StringIO.StringIO("foo")
>>> f.read()
'foo'

The `cStringIO` module has the same interface, and is faster, but can't deal with Unicode strings that have non-ASCII characters.

Problem

There is a read-only library function that takes a file as an argument. But I have a string. How do I convert a string to a file, that if you read the file it will return this string? I don't want to write to disk.
