Be sure to list a literal of the appropriate type e.g. 7.0 rather than 7 for a float, string literals in quotes '7'.Consider the following code:
things_that_burn = ['witches', 'wood', 'more witches']
What does this expression reduce to:
things_that_burn[2]

Question

BlackTom AI · Accepted Answer

The question presents a Python list and asks what the expression things_that_burn[2] evaluates to.
First, recall that Python uses zero-based indexing for lists, so index 0 is 'witches', index 1 is 'wood', and index 2 is the third element in the list.
Next, examine the list: ['witches', 'wood', 'more witches'] — the third item here is the string 'more witches'.
Note that string literals in Python are represented with quotes, so the value you retrieve is exactly the string with those characters: 'more witches'.
Since there are no alternative answer choices provided to compare against, we focus on what the expression yields given the list order: it yields the element at position 2, which is 'more witches'.
A common misunderstanding would be to start counting from 1, which would incorrectly point to 'wood' as index 2; that would be incorrect because the counting starts at 0. Another pitfall would be assuming a numeric result or another data type, but this retrieval returns a string value exactly as it appears in the list.
In summary, indexing [2] returns the third element, and for this list, that element is the string 'more witches'.
