>>> int('555')
555

In general, if there is a conversion defined between two types then you do 
the conversion by calling the destination type. So calling int() will 
convert a string, float, or long to an int (but it won't convert a complex 
number); calling str() will convert just about anything to a string; 
calling list will convert other sequences into a list and so on.

>>> int(3j)

Traceback (most recent call last):
  File "<pyshell#7>", line 1, in -toplevel-
    int(3j)
TypeError: can't convert complex to int; use int(abs(z))
>>> int(4.6)
4
>>> str(3.5)
'3.5'
>>> list('hello')
['h', 'e', 'l', 'l', 'o']
>>>
