creating a temporary file in python3

[wingnut2626]

import tempfile
a = tempfile.TemporaryFile(prefix='myfile',suffix='tmp')

>>> a.write('hello temp world')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' does not support the buffer interface

what do i need to do so that i can write to the tempfile? The documentation says that the default mode is sufficient......

This is to do with Unicode strings versus bytes strings. You need

a.write(b'hello temp world')

[MadCow108]

its better to be explicit about the encoding:

a.write('hello temp world'.encode("UTF-8"))

just casting to bytes will fail if the string does not only contain ascii (which it can in python3).
