hex() is a function, not a command.  And it only takes the one 
parameter, the int to be converted.

For more generality, try the str.format() method.  The x type converts 
to hex without any prefix, and then you can add the width and fill field.

http://docs.python.org/2/library/stdtypes.html#str.format
http://docs.python.org/2/library/string.html#formatstrings
http://docs.python.org/2/library/string.html#format-specification-mini-language

For starters, try:

print "0x{0:0>2x}".format(12)
or
print "0x{0:0>2X}".format(12)
     if you like uppercase hex characters
