tempfile

module

Temporary files and directories with unique names that clean themselves up after use.

Syntax

import tempfile

tempfile creates temporary files and directories with unique names and no races: TemporaryDirectory and NamedTemporaryFile used in a with block clean up after themselves. A hand-made path like /tmp/data.txt, by contrast, collides with other processes and is left behind. mktemp is deprecated: another process can grab the name between choosing it and creating the file — use mkstemp instead.

Examples

import tempfile, pathlib
with tempfile.TemporaryDirectory(dir='.') as d:
    p = pathlib.Path(d) / 'note.txt'
    p.write_text('draft')
    print(p.read_text())  # → draft
print(p.exists())  # → False — каталог удалён вместе с файлом
