• Automatically set the file permissions.

Installation

pip install writer-cm

Usage

from writer_cm import writer_cm

with writer_cm("file.txt") as temp:
    with open(temp, mode="w") as fh:
        fh.write("foo")

with open("file.txt") as fh:
    assert fh.read() == "foo"

Pass overwrite=True to overwrite an already existing file; an error is thrown otherwise:

with writer_cm("file.txt", overwrite=True) as temp:
    with open(temp, mode="w") as fh:
        fh.write("bar")

with open("file.txt") as fh:
    assert fh.read() == "bar"
