You need to be careful of integer division.  


In [16]: 57/7
Out[16]: 8

In [17]: 57.0/7
Out[17]: 8.1428571428571423

If you want to insure floating point division, with recent versions of
python do

  from __future__ import division
  print 57/7

Otherwise, you can do  

  print float(x)/y

To format 2 significant digits of a floating point number, you can do

print '%1.2f' % (57.0/7)

The man pages of the C function sprintf will tell you a lot about the
format possibilities:
