QUESTION
ANSWER
Answered 2020-Jan-06 at 15:54The value of AsyncFunctionDef is never needed at runtime, only by mypy in two Python-2-compatible type hints (at lines 1298 and 1318). The if False prevents the assignments from occurring at run-time, but lets mypy see the correct underlying type to use during type-checking. (It also prevents an ImportError from being raised at the attempt to import the typing module under Python 2.)
It would be clearer to use typing.TYPE_CHECKING (whose value is False at run-time, but True when mypy runs) here, except typing.TYPE_CHECKING is also unavailable in Python 2.
QUESTION
I am trying to convert a module from python version 2.x to python version 3.x. To do that I am using 2to3 converter. However since I couldn't find any parameter in this converter to change also %s or printf-style to str.format() style I just tried to use pyupgrade package as follows:
pyupgrade /path/to/myfile.py
However this one also does not make any change. Do you have any idea or suggestion if there is a converter to do this?
Ex.

Answered 2019-Oct-07 at 15:12The project either has some bugs in this area, or they deliberately ignore code not meeting minimal formatting requirements.
Your sample fails because there are no spaces between the ' and % characters:

Install pyupgrade
You can use pyupgrade like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
