Passing stages=[1] or stages=[2] passes the flag ``--stage1`` or ``stage2`` to ``futurize``. Passing both stages runs ``futurize`` with both stages by default. If from3 is False, runs ``futurize``, converting from Python 2 to both 2 and 3. If from3 is True, runs ``pasteurize`` to convert from Python 3 to both 2 and 3. Optionally reformats the code block first using the reformat() function. If run is True, runs the resulting code under all Python interpreters in self.interpreters. )�stages� all_imports�from3� conservative)� interpreter)r �_write_test_script�_futurize_test_script�_read_test_scriptr@ �_run_test_script) r1 r rN rO rP Zreformat�runrQ r0 rR �_r r r �convert� s zCodeHandler.convertc C sp |r| � |�}| � |�}t|t�r6t|t�s6|�d�}t|t�rTt|t�sT|�d�}| �t|�� �|�� � dS )a� Compares whether the code blocks are equal.

If a different type of warning is triggered, it will not be handled: depending on the other warning filtering rules in effect, it might be silenced, printed out, or raised as an exception. If called with callable_obj omitted or None, will return a context object used like this:: with self.assertWarns(SomeWarning): do_something() An optional keyword argument 'msg' can be provided when assertWarns is used as a context object. The context manager keeps a reference to the first matching warning as the 'warning' attribute; similarly, the 'filename' and 'lineno' attributes give you information about the line of Python code from which the warning was triggered.
