When you call the Cython function in your Python code, send the entire NumPy array object as an argument for that function call. Perform all the iteration over the object in Cython .

If you just use plain python, there is no array. Both the visual module and the pylab module load numpy. And you can still index the array as you would a list. Here is an example.

In Python, arrays map directly to lists. Tables in TOML. A table is a collection of key-value pairs in a TOML file, labeled with a header in square brackets.
