Here’s how to use Cython to accelerate array iterations in NumPy. NumPy gives Python users a wickedly ... only use Cython for the part of your program that does the actual computation.

$ python iterator_test.py 463 926 1389 1852 Let’s take a look at what’s going on. We made our own class and defined a __next__ method, which returns a new iteration every time it’s called.

Sometimes when using a condition-controlled (WHILE) loop there may be a situation where the code contained within the iteration is never run. This is because the condition is tested at the start ...
