String formatting can do what you want:
>>> "%04X"%65
'0041'
>>> "%04X"%15
'000F'

For more info (and the meaning of the syntax) see chapter 2.2.6.2 of the
library reference (String Formatting Operations):

ps. the above solution pads to number to get a four-digit one, but won't
truncate it, resulting in:
>>> "%04X"%65000000
'3DFD240'
I don't really think you want to truncate (as that will mangle the number,
loosing information).
