When I create a temporary directory, the name doesn't come back in a way the application expects it.  I ran into this using gitPython and I'm not entirely clear whether it's a tmpfile issue or a gitpython issue, but I think it's tempfile.  

Repro:

In [12]: td = tempfile.TemporaryDirectory()

In [13]: td.name
Out[13]: '/var/folders/kd/bjhw84ss2x734frx98qh1mw40000gn/T/tmpgralfh9m'

In [14]: str(td)
Out[14]: "<TemporaryDirectory '/var/folders/kd/bjhw84ss2x734frx98qh1mw40000gn/T/tmpgralfh9m'>"

The problem with this is that gitPython takes a temporary directory as an argument and effectively does a mkdir(str(td)), which creates a weird directory in /var/tmp:

eosborne@eosborne-salt-master:/tmp$ ls -alhd *Temp*
drwxrwxr-x 3 eosborne eosborne 4.0K Jan 27 12:42 '<TemporaryDirectory '\'''



I believe that str(td) should return just the directory name and that repr(td) can return the extra bit of text with "<TemporaryDirectory ..>" but that's just my two cents.

I have thrown this issue up on the gitPython list too: https://github.com/gitpython-developers/GitPython/issues/1115
