Another efficient way of doing this is:

import sys
a = 0.5
sys.stdout.write(str('%0.2f'%a))

 f = 4.55556
 print "{0:.2f}".format(f)

There is also a special module for fixed point decimals. More: http://docs.python.org/library/decimal.html

print "{0:.2f}".format(your_number)

This is explained in detail in the Python Documentation.

x = 4.12121212
print '%.2f' % x

Basically, the same way you'd do it in C with printf.
