How to specify text mode in Python's tempfile.TemporaryFile()?

Question

In the documentation , TemporaryFile() mentions

The returned object is a file-like object whose _file attribute is either an io.BytesIO or io.StringIO object (depending on whether binary or text mode was specified)...

However, as of Python 3.6, there is no text=True method of asking for text mode. How does one do it?

Answer 1

TemporaryFile signature:

 tempfile.TemporaryFile(mode='w+b', buffering=None, encoding=None, newline=None, suffix=None, prefix=None, dir=None)

We are interested in a mode parameter. The last symbol is 'b', which means binary mode. If you pass mode='wt' , it will be opened in a text mode.

All modes are described on this page: https://docs.python.org/3/library/functions.html#open
