If using Python >=3.4, you also have [https://docs.python.org/3/library/pathlib.html <code>pathlib</code>] | |||
<syntaxhighlight lang="python"> | |||
from pathlib import Path | |||
p = Path("my_folder") | |||
# Join paths | |||
pp = Path(p, "files.tar.gz") | |||
pp.suffix # returns ".gz" | |||
pp.suffixes # returns [".tar", ".gz"] | |||
pp.name # returns "files.tar.gz" | |||
pp.parent # returns "my_folder" | |||
</syntaxhighlight> | |||

* One annoyance with <code>pathlib.Path</code> is that you need to convert things to strings manually | |||
** This can be done with <code>str<code>, <code>.resolve()</code>, or <code>os.fspath()</code> | |||
