Python precision in string formatting with float numbers

Question

I don\'t understand why, by formatting a string containing a float value, the precision of this last one is not respected. Ie:

\'%f\' % 38.2551994324
         


        

Answer 1

I would use the modern str.format() method:

>>> '{}'.format(38.2551994324)
'38.2551994324'

The modulo method for string formatting is now deprecated as per PEP-3101
