Question
Which of these code snippets will return the name "Harry" from the following list ?nameList = ["John", "Harry", "Jesse", "John", "Harry", "Harry"]AnameList()BnameList[1]CNameList(4)DnameList["4"]
Solution 1
The correct code snippet that will return the name "Harry" from the list is BnameList[1].
Here's why:
A. nameList() - This is incorrect because it's trying to call nameList as a function, which it's not. It's a list.
B. nameList[1] - This is correct. In Python, list indices start at 0, so nameList[1] will return the second item in the list, which is "Harry".
C. NameList(4) - This is incorrect because it's trying to call NameList as a function, which doesn't exist. Also, it's case-sensitive and should be nameList.
D. nameList["4"] - This is incorrect because the index should be an integer, not a string. It should be nameList[4] to access the fifth item in the list. However, this would return "Harry" as well, but it's not the correct answer to this question as it's asking for the first occurrence of "Harry".
Solution 2
The correct code snippet that will return the name "Harry" from the list is BnameList[1].
Here's why:
In Python, lists are indexed starting from 0. So, nameList[1] will return the second element in the list, which is "Harry".
Option A, nameList() is incorrect because it tries to call the list as a function, which will result in an error.
Option C, NameList(4) is incorrect because it tries to call a non-existent function NameList. Also, even if it was nameList[4], it would return the fifth element in the list, not "Harry".
Option D, nameList["4"] is incorrect because it tries to use a string as an index. In Python, list indices must be integers.
Solution 3
The correct code snippet that will return the name "Harry" from the list is BnameList[1].
Here's why:
In Python, lists are indexed starting from 0. So, the first element in the list is at index 0, the second element is at index 1, and so on.
In the given list, "Harry" is the second element, so it's at index 1. Therefore, nameList[1] will return "Harry".
The other options are incorrect because:
AnameList() and CNameList(4) are invalid because they're trying to call the list as if it's a function, which is not correct.
DnameList["4"] is incorrect because it's trying to use a string as an index, which is not valid. Indices must be integers.
