Opens a Gio.File as a Python file object

Project description

Opens a Gio.File as a Python file object

def open(file, mode="r", buffering=-1, encoding=None, errors=None,
         newline=None, cancellable=None):
    """
    Like io.open() but takes a Gio.File instead of a filename.

    The only modes supported are r/rw/rb/r+b
    Takes a cancellable kwarg for passing a Gio.Cancellable().
    Cancelling it will abort any ongoing blocking operation.

    Returns a io.IOBase instance.
