Question

Choose the function that will result in a 3 on the next line.

>>> aList = [3, 10, 10, 10, 30, 30]
>>> aList. ___(10)
count
index
pop

Answer 1

To count the occurrences of the number 10 in the given list aList, you should use the `count` method.

Step-by-step explanation:

The correct function to use in this case is `count`.

>>> aList = [3, 10, 10, 10, 30, 30]

>>> aList.count(10)

3

The `count` method in Python is used to count the number of occurrences of a specified element in a list. In this example, `aList.count(10)` returns 3 because the value 10 appears three times in the list `[3, 10, 10, 10, 30, 30]`. Therefore, using `count(10)` on `aList` will result in 3, and this is what will be returned on the next line.

Answer 2

Answer: count

Step-by-step explanation:

Given the program :

>>> aList = [3, 10, 10, 10, 30, 30]

>>> aList. ___(10)

To obtain a value of 3 on the next line, we use the count function :

aList.count(10)

The above statement returns the number of occurrences of digit 10 in the list aList. Digit 10 occurs 3 times in the list. Hence, output will be 3

The index function returns the lowest index where the digit 10 appears and thus it will give an output of 1

The pop function to used to deletes item belonging to a specified index and returns the item which is removed, for this exercise, selecting the pop function will throw an error as the list does not have any item with the index 10.
