Let me answer your query one at a time. The unique identifier is being created here using the index column that we are adding. This is being done to split the dataset into train and test set. Once you run the code you will be able to view it.

Now, the Python hashlib hashing function takes variable length of bytes and converts it into a fixed length sequence. This is a one way function which means, you hash a message, you get a fixed length sequence. But you cannot get the original message from those fixed length sequence.
