Write Eye-tracking data to file

I want to write real-time eye-tracking data in file while vizard is running. I want my data values to get store upto 5 decimal places as tobii eyetracker is giving values upto 16 decimal places, If i use %s for writing but not working for %f. My code is:
data = '\t%f\t%f\t\t%f\n'%(st,gaze_left_eye1,gaze_right_e ye1)
f1.write(data)

Why this code not working?

The string formatting page has different examples of formatting data including the number of digits after the decimal point.
