hi Francesco, 
 
couldnt get hex of bin working on IDLE Python 2.5 when i type: 
 
>>> hex(0b1001001001001001001)
SyntaxError: invalid syntax
>>> bin(0x49249)
Traceback (most recent call last):
  File "<pyshell#126>", line 1, in <module>
    bin(0x49249)
NameError: name 'bin' is not defined
 
pls advise.
