It is possible to use generic Python objects as the dtype for a NumPy array, but if you do this, you’ll get no better performance with NumPy than you would with Python generally.

This tells Python to import SymPy into the main namespace, define a symbolic x variable, and set up "pretty printing." This will make the output look more like it does in a math textbook.

Interpreting math expressions is one of those things that seems simple until you get into it. The first problem is correctly lexing the input — a term that means splitting into tokens.

The solution he came up with is to use the Python interpreter as a binary math aide. We knew that you could use Python to convert between decimal, hexadecimal, and binary.
