Answer 1

Numpy arrays are way faster than python built-in data types like list, because of several reasons. I'm pointing out some of the important ones:
1. Numpy array is highly compact than python list as list can have different data types inside them which basically reduces speed.
2. Numpy is implemented in highly optimized C code.
3. Numpy array uses vectorization by which it can make use of vector ALU rather than scalar ALU of the processor. And vector ALU is super fast in operations involving arrays
