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

If you can live with 3. and 3.0 appearing as "3.0", a very simple approach that right-strips zeros from float representations:

print("%s"%3.140)
