Python Day 22 – practice makes humble

I just went over previous practice problems I’d already done and wow I did not realize how much I had forgotten. It definitely went faster but still… there’s much more work to do.

I learned:

To select a column in a numpy array is “arr[::1, 2::]”. And when you’re getting the type you just put type(arr), rather than arr.type which I tried many times.

A little thing I shall soon learn:

IN WHAT SITUATIONS DOES ONE USE () VERSUS []? Today really made me realize that I’ve been using them interchangeably and that is wrong. Oh well I shall ask a friend.

Talk to ya later 🙂
