This is my code, trying to convert the second field of the line from exponential into float.
outputrrd = processrrd.communicate() (output, error) = outputrrd
This work for me, try it out.
def remove_exponent(value): decial = value.split('e') ret_val = format(((float(decial[0]))*(10**int(decial[1]))), '.8f') return ret_val
