Hey everyone, after some tries and a bit of research I managed to make code work. Can someone help me understand why the "X" 's disappear after I write "message = garbled[len(garbled)::-2]"? I am pretty sure it's an easy answer but I'm a bit confused here, thanks!
garbled = "!XeXgXaXsXsXeXmX XtXeXrXcXeXsX XeXhXtX XmXaX XI"
message = garbled[len(garbled)::-2]
