[issue40620] Range tutorial shorthand could be made clearer

Terry J. Reedy added the comment: This block is the same in 3.9 and 3.8. My first though is this block is a holdover from 2.7, where range returned list. But looking at what is written previously, I think your interpretation is correct -- and agree that something other that code and corresp

[issue40633] json.dumps() should encode float number NaN to null

Raymond Hettinger added the comment: [Eric] > this is documented behavior [Mark] > I definitely wouldn't want to see nans translated to > "null" by default. I concur with both of these statements. I would support adding an option (off by default) to convert NaNs to None. While NaNs were o

[issue40633] json.dumps() should encode float number NaN to null

Raymond Hettinger added the comment: One other issue just came to mind. While we could convert NaN to null during encoding, there isn't a reasonable way to reverse the process (a null could either be a NaN or a legitimate None). That would limit the utility of a new optional conversion. -
