Hi @Ev2geny, good catch! I've left a comment on the issue with some comments on the proposed solution. Could you change the PR to reflect that?

What I'm suggesting is to create a new context manager TemporaryFilePath() that returns a temporary file path (without creating it) and to delete it after it is used.

If you don't know context managers (that's what the with thing is) you could read this.

@pietermarsman , I think this is logical to do. I will re-write PR with context manager TemporaryFilePath()

[Ev2geny]

I have implemented context manager. All tests pass, except the ones on Python 3.4.
Since support for 3.4 is already decided to be dropped for pdf miner (#503) I assume I assume I can just wait for (#503) to be fixed

[pietermarsman]

Yep, lets wait for #503. The error is caused because prefix and suffix are directly added to the filename. I guess the default values are different in python 3.4 (e.g. empty string).

[pietermarsman]

I removed python 3.4 from the following release. Could you rebase on develop and force push?
