Question

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

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

A) aList.count(10)
B) aList.index(10)
C) aList.pop()

Answer 1

The correct function to choose is aList.count(10) as it will return the value 3 from the given list. The other functions will return different results.

Step-by-step explanation:

To get a 3 on the next line, you need to choose the function that will return the value 3 from the given list. Let's analyze the options:

• A) aList.count(10): This function will return the count of occurrences of the number 10 in the list. Since there are three 10s in the list, this function will return 3. This is the correct choice.
• B) aList.index(10): This function will return the index of the first occurrence of the number 10 in the list. Since the first occurrence is at index 1, this function will return 1.
• C) aList.pop(): This function will remove and return the last element of the list, which is 30 in this case.

So, the correct choice is A) aList.count(10).
