How can I create a temporary directory and get its path/file name in Python?

In Python 3, TemporaryDirectory from the tempfile module can be used.

From the examples:

import tempfile

with tempfile.TemporaryDirectory() as tmpdirname:
     print('created temporary directory', tmpdirname)

# directory and contents have been removed

To manually control when the directory is removed, don't use a context manager, as in the following example:

import tempfile

temp_dir = tempfile.TemporaryDirectory()
print(temp_dir.name)
# use temp_dir, and when done:
temp_dir.cleanup()

The documentation also says:

On completion of the context or destruction of the temporary directory object the newly created temporary directory and all its contents are removed from the filesystem.

At the end of the program, for example, Python will clean up the directory if it wasn't removed, e.g. by the context manager or the cleanup() method. Python's unittest may complain of ResourceWarning: Implicitly cleaning up <TemporaryDirectory... if you rely on this, though.

If I get your question correctly, you want to also know the names of the files generated inside the temporary directory? If so, try this:

import os
import tempfile

with tempfile.TemporaryDirectory() as tmp_dir:
    # generate some random files in it
     files_in_dir = os.listdir(tmp_dir)

Docs.python.org TemporaryDirectory example using a context manager

import tempfile
# create a temporary directory using the context manager
with tempfile.TemporaryDirectory() as tmpdirname:
    print('created temporary directory', tmpdirname)
# directory and contents have been removed

Using pathlib to facilitate path manipulation on top of tempfile makes it possible to create new paths using the / path operator of pathlib:

import tempfile
from pathlib import Path
with tempfile.TemporaryDirectory() as tmpdirname:
    temp_dir = Path(tmpdirname)
    print(temp_dir, temp_dir.exists())
    file_name = temp_dir / "test.txt"
    file_name.write_text("bla bla bla")
    print(file_name, "contains", file_name.open().read())

# /tmp/tmp81iox6s2 True
# /tmp/tmp81iox6s2/test.txt contains bla bla bla

Outside the context manager, files have been destroyed

print(temp_dir, temp_dir.exists())
# /tmp/tmp81iox6s2 False
print(file_name, file_name.exists())
# /tmp/tmp81iox6s2/test.txt False
