Methods to increase the execution speed of Python code

Now we are going to define a few of Python's normal magic methods, which will allow us to iterate over the values stored in our object and access them by indexing. For this, refer to the following code example:

The thing to notice in this code example is how little has changed from what we've be doing in a pure Python implementation. The only real differences are the type definitions we provided for every parameter and the local variable.

We didn't actually have to provide the type definition for every parameter and local variable. The type definition lets Cython generate plain C code ...
