      "sought out", not "sort out". But I completely agree with your assessment.

    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.

      So you need someone who (probably understands the topic and) fills in the blanks for you?
      Or just someone who points you to the location of the tutorial materials, noted in the video summary.

    • @pjmmccann
      @pjmmccann 2 ปีที่แล้ว +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.
