Why NumPy Isn’t Really Python

NumPy often feels different from the rest of Python, fewer loops, more global operations, strange broadcasting rules, and error behavior that doesn’t always match normal Python expectations. This video explains why that’s not an accident. We step away from syntax and look at the deeper design choice NumPy makes: optimizing for memory and hardware instead of Python’s object and control-flow model. Broadcasting isn’t a convenience feature, it’s a shape-alignment rule. Silent inf values aren’t carelessness, they mirror how floating-point hardware behaves. Views that share memory aren’t unsafe, t…
