将元素的值分配给变量输出

Question

So, I'm on a beginner's python course on coursera and there is a question I just don't understand:

Assign the value of the 34th element of lst to the variable output .

Here is the list:

1st = ["hi", "morning", "dog", "506", "caterpillar", "balloons", 106, "yo-yo", "python",
       "moon", "water", "sleepy", "daffy", 45, "donald", "whiteboard", "glasses",
       "markers", "couches", "butterfly", "100", "magazine", "door", "picture", "window",
       ["Olympics", "handle"], "chair", "pages", "readings", "burger", "juggle", "craft",
       ["store", "poster", "board"], "laptop", "computer", "plates", "hotdog", "salad",
       "backpack", "zipper", "ring", "watch", "finger", "bags", "boxes", "pods", "peas",
       "apples", "horse", "guinea pig", "bowl", "EECS"]

What am I supposed to do with this thing? I'm not looking for anyone to straight up give me the answer, but rather help me understand what the question wants from me and how to solve it.

Answer 1

output = 1st[34]

“所以这就是它所说的，通过索引列表，您可以获得值并将其分配给变量输出”

Answer 2

To index a list, the correct syntax is:

list[i] where the i is the index of the element you want to retrieve. So in your case:

output = 1st[34]

Good luck with Corsera!

Answer 3

yeah. i ended up figuring it out on my own. but a big thanks to both of you, regardless.

so yeah, I did this (in case anyone else ever gets stuck on something like that as well):

you need to find index 34 because python is 0 index

output of that will be "laptop"

print(lst[34])

now you need to assign the value "laptop" (35th element) to the variable "output"

which looks like:

output = "laptop"
print(output)

Answer 4

The indexing of the list starts from 0.
Therefore, to access the 34th element in the list, you need to enter the index 33 .
The code should then be like this:

1st = ["hi", "morning", "dog", "506", "caterpillar", "balloons", 106, "yo-yo", "python",
       "moon", "water", "sleepy", "daffy", 45, "donald", "whiteboard", "glasses",
       "markers", "couches", "butterfly", "100", "magazine", "door", "picture", "window",
       ["Olympics", "handle"], "chair", "pages", "readings", "burger", "juggle", "craft",
       ["store", "poster", "board"], "laptop", "computer", "plates", "hotdog", "salad",
       "backpack", "zipper", "ring", "watch", "finger", "bags", "boxes", "pods", "peas",
       "apples", "horse", "guinea pig", "bowl", "EECS"];
output = lst[33];
