Tested in Python 3 3 2 There are many ways to accomplish this  here s one of the shortest  using only python-provided stuff   import base64 hex data   57696C6C20796F7520636F6E76657274207468697320484558205468696E6720696E746F20415343494920666F72206D653F2E202E202E202E506C656565656173652E2E2E212121  ascii string   str base64 b16decode hex data   2 -1  print  ascii string    Of course  if you don t want to import anything  you can always write your own code  Something very basic like this   ascii string      x   0 y   2 l   len hex data  while y  lt   l      ascii string    chr int hex data x y   16       x    2     y    2 print  ascii string
