    This was very well done and very useful (despite the mishap with the left side of the screen 😊).
    Thank you also for including the part about memory allocation in numpy. It helped me finally understand when (and why) I can expect to get a view vs. a copy of an array. It didn't even seem like an advanced concept, but that's because Alex did a great job explaining it.

      Or just someone who points you to the location of the tutorial materials, noted in the video summary.

    • @pjmmccann
      @pjmmccann 2 года назад +1

      Just in case someone's reading this one year later ;-) The element with index 3 is 13, but it's not included in a[1:3], or in a[1,-2]. Remember that the right hand side boundary of the slice isn't included, so a[1:3] means the elements with indices 1 and 2. The same goes for a[1:-2], it's an array consisting of the elements starting at a[1] and ending at the element *before* a[-2]. Alex did mention this early on in the talk, and it's consistent with the behaviour of ranges in python. It might be easiest to think of [1:3] as "really" being [1,3), in the spirit of a half-closed, half open interval.
