Consider the following line of code:

somelist = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]

Which one of the following options is a valid line of code for displaying the element at the twenty-second position in the list?

Question

Consider the following line of code:

somelist = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n",  "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]

Which one of the following options is a valid line of code for displaying the element at the twenty-second position in the list?

BlackTom AI · Accepted Answer

First, let's restate what the question is asking: we need a valid line of code that displays the element at the twenty-second position in the given list. In Python, list indices are zero-based, so the twenty-second element is at index 21.

Option 1: somelist(21)
This uses parentheses like a function call, but somelist is a list, not a function. Calling somelist(21) is a TypeError because lists are not callable. Thus this is invalid syntax for accessing a list element.

Option 2: somelist[21]
This uses the correct bracket notation to access the element at index 21. However, simply writing somelist[21] would retrieve the value but not display it unless you are in an interactive shell where the value is echoed, or you assign it to a variable or print it. Since the prompt asks for a line of code to display the element, this alone is not guaranteed to display the value in a typical script.

Option 3: print(somelist(21))
This combines a function-call syntax with a print statement, but somelist(21) is invalid for the same reason as Option 1: lists aren’t callable. Therefore this line would raise an error before printing anything.

Option 4: print(somelist[21])
This line correctly uses indexing inside the print call to display the element at index 21 in Python. It follows the proper syntax for accessing a list element and printing it, ensuring the value is shown when the code runs.

In summary, the only option that both accesses the correct element by index and outputs it via print is Option 4: print(somelist[21]). The other choices either use invalid syntax for lists, rely on an interactive display that may not occur in a script, or attempt to call a non-callable object.
