To create an array in Python, we can use a type of variable called a “dictionary.” This is an associative array, meaning that it is made of value/key pairs. This looks like so: ...

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 .
