Not really.  It might be a bit obfuscated, but

use Chris's suggestion about hashing.

That said, if the user has access to the source code, there's nothing
preventing them from changing

  if hash(provided_password) == existing_hash:
    do_magic()

into just

  if True:
    do_magic()

and re-running the program.
