This is fine (although using the string module constants is
probably still a good idea!) because you are returning a list
then checking to see if original is in that list
> print binary[:26]
But this isn't because you are again generating a list and
printing all of it. You need to find the index of your
character within the list and then use that to index binary:
if original in alphabet[:26]:
When stuck it's worth reading the documentation carefully to
check what types each action expects and returns. Also to
browse the list of available functions and constants.
There is a saying that "Python comes with batteries included"
which means that usually you can find something in the library
that will do the bulk of your job for you.
The pyhon >>> prompt is your friend here because it makes it
very easy to try ideas before committing them to a module/program.
Of course sometimes we just want to experiment and do things for
the sake of finding out how. That's OK too. :-)
