I am using black formatter. I have two newlines before and two newlines after function definition. I want one newline before and one newline after function definition.
Can i do it using black config file black --config FILE. If so,how.
Using black formatter this is NOT possible. From it's documentation:
By using it, you agree to cede control over minutiae of hand-formatting._
It uses 2 lines to visually distinguish methods from empty lines in code structure. From the docs: Black will allow single empty lines inside functions, [...] It will also insert proper spacing before and after function definitions. It’s one line before and after inner functions and two lines before and after module-level functions and classes.
From: the docs of black.readthedocs.io
Command line options Black has quite a few knobs these days, although Black is opinionated so style configuration options are deliberately limited and rarely added. You can list them by running black --help.
You need to change the formatter you use to something different to get your effect.
