Sometimes you need a file-like object when all you have is an iterator, for instance when using psycopg2's cursor.copy_from. This class will handle the impedance mismatch.
import io
import sys
class IteratorFile(io.TextIOBase):
""" given an iterator which yields strings,
return a file like object for reading those strings """
def __init__(self, it):
self._it = it
self._f = io.StringIO()
