What’s Coming in Python 3.8
“The Python 3.8 beta cycle is already underway, with Python 3.8.0b1 released on June 4, followed by the second beta on July 4. That means that Python 3.8 is feature complete at this point, which makes it a good time to see what will be part of it when the final release is made.”

PyLint False Positives
“In some recent discussion on Reddit, I claimed that, for cases where I’m already using flake8, it seemed as though 95% of Pylint’s reported problems were false positives. Others had very different experiences, so I was intrigued enough to actually do some measurements.”
