Answer 1

The answer by smarx opens the file by specifying path. It is, however, easier to specify fd instead. In that case the context manager closes the file descriptor automatically:

from tempfile import mkstemp

fd, path = mkstemp()

# use a context manager to open (and close) file descriptor fd (which points to path)
with open(fd, 'w') as f:
    f.write('TEST\n')

# This causes the file descriptor to be closed automatically
