How do you rename temp files in Python?

2 Answers. You can access the filename via f.name . However, unless you use delete=False python will (try to) delete the temporary file automatically as soon as it is closed. Disabling auto deletion will keep the tempfile even if you do not save it - so that's not such a good idea.

How do you create a temp list in Python?

Reading and Writing to a Temporary File

The write() method is used to write to a temporary file. It takes input as binary data by default. We can pass the string to be written as input, preceded by a 'b' to convert it to binary data. The write function returns the number of characters written.

How do you use NamedTemporaryFile in Python?

You just want a file object (pointing to an empty file) which has a filename associated to it and hence you cannot use a StringIO object: from tempfile import NamedTemporaryFile f = NamedTemporaryFile() # use f .. Once f is garbage collected, or closed explicitly, the file will automatically be removed from disk.
