We take the item at the second last index.

I tried some_array[0:4], but it didn't work

np.array(some_array[:5])

Isn’t there like 2 methods

Raghav Pant

21:43

Three, one is python inbuilt, the other is an array method, and one is a numpy pethood.

Raghav Pant

21:43

*method

Vedan Desai

np.mean(some_array[:6])

This question is super trivial…but what does the “nd” in np.ndarray signify?

Candy.get(

Xuzhe Zhi

use sort

Kyle Znachko

32:01

candy.get(‘win percent’)

JARED DISHMAN

32:03

np.array(candy.get("winpercent").index[0:5])

CHANINDER RISHI

32:12

Get win percent column

CHANINDER RISHI

32:17

And sort by

JARED DISHMAN

32:27

ah crap I forgot to sort

Raghav Pant

34:51

Is the "np.array" prior required? Mine worked fine without it.

Teresa Lee

39:04

can we just find the length of the first column?

CHANINDER RISHI

39:31

Wait so the columns of caramel and chocolate just consisted of 0’s and 1’s right? To represent yes and no if they have them or not…

CHANINDER RISHI

Wrd ok thank you

The last one in Boolean indexing

Jaeda Gantulga

is most or all of the reference sheet going to be used for DSC 10?

Raghav Pant

43:36

Could we go up a little to 2.3, please? I didn't see the last line.

Raghav Pant

43:46

Ah, thank you.

Vedan Desai

56:07

agreed

Medha Upadhyay

56:11

yes :)

Christine Deng

01:02:39

I'm confused because when I ran the code without .index[0] there are multiple candies with the same number?

Medha Upadhyay

01:02:56

^^ how do you decide which one is the answer

Christine Deng

01:03:49

^^ do you just default pick the top one with index[0]?

Christine Deng

01:04:55

thank you!

Teresa Lee

01:05:32

are the columns containing the binary numbers each arrays?

Teresa Lee

01:05:58

Teresa Lee
