String Formatting in Python

• Often you'll want some control over how your values are printed out
• Python provides C-like format strings
• Uses the special % operator after a string, followed by a value, or tuple of values to fill it in
• Works just fine in assignment too!

>>> "%s %s!" % ('hello', 'world')
'hello world!'
>>> ugly_price = 24.32203952
>>> formatted_price = "%.2f" % ugly_price
>>> print formatted_price
24.32
