Formatting floats without trailing zeros

Question

How can I format a float so that it doesn\'t contain trailing zeros? In other words, I want the resulting string to be as short as possible.

For example:

<         


        

Answer 1

Me, I'd do ('%f' % x).rstrip('0').rstrip('.') -- guarantees fixed-point formatting rather than scientific notation, etc etc. Yeah, not as slick and elegant as %g, but, it works (and I don't know how to force %g to never use scientific notation;-).
