Clearly it doesn't play a big role for 3 dimensional arrays, but for a higher number of dimensions caching could become pretty important (as we will see, there are at most 8 dimensions, so it is not that clearly cut, whether this caching is really worth it). I check the six module, and yes, it doesn't include a single word named "memoryview". Making statements based on opinion; back them up with references or personal experience. The easiest fix is to drop the decode () property on the string objects and call it directly to resolve the issue as it's already in the decoded format. include bytes and bytearray. The Journey of an Electromagnetic Wave Exiting a Router. You can't attach it to the existing_array argument, as that will make a slice of that array, instead of telling the memoryview constructor some slice parameters.
