When you loop over the reshaped arrays, whole rows (np.ndarray's) are assigned to b (and a) at a time, which are mutable objects, meaning that you are allowed to stick in new integers at will, which happens when you do a += 1. Using sudo -i is virtually the same as the sudo su command. Due to their small size, they cannot be guided accurately and generate high amounts of friction. If a specific method is not defined, the augmented assignment falls back to the normal methods.

I know i++ increments it by 1, but what does ++i do? After running each for loop, A has not changed, but B has had one added to each element. This is because now C is a 1D array (C.ndim == 1), and so when iterating over C, each integer element is pulled out and assigned to c. Now in Python, integers are immutable, meaning that in-place updates are not allowed, effectively transforming c += 1 into c = c + 1, where c now refers to a new integer, not coupled to C in any way.

If you don't understand the difference, you'll run into weird linker errors like "undefined symbol foo" or "undefined reference to 'foo'" or even "undefined reference to vtable for foo" (in C++). Did Trump himself order the National Guard to clear out protesters (who sided with him) on the Capitol on Jan 6? So if you, for example, attempt to add a complex value to a real valued numpy array, the in place add will remain real valued, whereas if you use reassignment, you get the correct complex result. As it happens your bs are numpy.ndarrays which implements __iadd__ and return itself so your second loop modifies the original array in-place. The resulting offspring of asexual reproduction are genetically identical to each other and also identical to their parents, whereas offspring of sexual reproduction differ from each other and also differ from their parents. Anaphase of Mitosis vs Anaphase I of Meiosis .
