Learning atomic parts of anything is very easy. Its using those atomic parts to build complex systems that is hard.
If there is a operator in Perl 6, which you don't have in Python- Your options are to rewrite those semantics in Python most of them pretty large, and they won't be easy to read either.
Ease of learning is a irrelevant metric. You can't use a needle to replace a saw, if you do you are only going to end up doing more work.
If you learn both by learning from a well-written book, then they are equally easy, though Perl, by its depth, might require a slightly bigger time investment.
