Real-time linting of Python with VSCode

Question

Recently I'm using VSCode as my Python IDE, and I install DonJayamanne/pythonVSCode, which supports linting. However, the linter only works when saving, but what I want is real-time linting. The workaround suggested by the author is to set files.autoSave to on, so that the linter will work whenever the file is automatically saved. There's a relevant discussion on Github, for your reference.

Since I don't want to turn on auto-save function, is there any way to do real-time linting of Python with VSCode? Or is there any suggested extension?
