pycharm/intellij running config environment variables spaces

Got bitten yet again when copypasting them - the name of one of them had four leading tabs. THAT DIDN”T GET SHOWN UNTIL I TRIED TO EDIT THE ENVIRONMENT VARIABLE IN THE PYCHARM WINDOW - it removes them when visualizing. Why? (The parameter of the last one had a trailing space too)

Python negative 0

-0.0 exists as float, and gets stored like this. Though it’s not less than 0 or +0.0. Can’t easily google a way to detect if it’s a negative 0 or not.
