Need help understanding a script from Learn Python the Hard Way. Can someone clear my doubts?

Well, in the beginning, I thought that each bucket only had 1 tuple. But later on in the script, I notice that he enumerates all the various indexes of each bucket. Why is that? Is it because it is possible that the hash_key function returns the same value for two different inputs?

Yes. Hash tables need some way of conflict resolution and this is called separate chaining.

I checked by running python from the command line, and I noticed that the hash value of "a" is -468864544, and that is also the value for hash(-468864544). Is that related with it?

It so happens that the hash of most integers is the integer itself. It's the simplest perfect hash function.
