You need to seek to the part of the file you want to read:
>>> x = tempfile.TemporaryFile()
>>> x.read() # file is empty to start with
''
>>> x.write('Nobody expects the Spanish Inquisition!')
>>> x.read() # current file is at the end of the file, so nothing to read
''
>>> x.seek(0) # move to the beginning of the file
>>> x.read()
'Nobody expects the Spanish Inquisition!'
>>> x.seek(7)
>>> x.write('EXPECTS')
>>> x.tell() # where are we?
14L
>>> x.seek(0)
>>> x.read()
'Nobody EXPECTS the Spanish Inquisition!'
