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_float = ['witches', 'lead', 'bridges', 'small pebbles', 'a church', 'a duck']
What does this expression reduce to:
things_that_float[2]

Question

BlackTom AI · Accepted Answer

First, let's restate the scenario to ensure the context is clear: we have a Python list named things_that_float containing six string elements: ['witches', 'lead', 'bridges', 'small pebbles', 'a church', 'a duck']. The expression being evaluated is things_that_float[2], which uses zero-based indexing to pick the element at position 2.
Option analysis:
Option: '\'bridges\'
        \'bridges\''
Here, the literal shown is a string containing the word bridges, which matches the element at index 2 of the list. Given zero-based indexing, index 0 is 'witches', index 1 is 'lead', and index 2 is 'bridges', so retrieving things_that_float[2] yields 'bridges'. This aligns with how lists are indexed in Python: the nth element is retrieved by using [n], counting from zero.
Why this correctly corresponds to the result: indexing into the list returns exactly the third item, and the literal representation of that item is the string 'bridges' including its surrounding quotes.
Why there could be confusion in the formatting: the provided answer option shows a quoted string representation, which is consistent with how Python would display a string value when printed or when shown as a literal. If someone expected an unquoted value, that would be a misunderstanding of Python’s string literals.
If there were alternative options, we would compare them along these lines: ensure the index used is 2 (not 1 or 3), confirm zero-based indexing, and verify that the list element at that index is indeed 'bridges' and not some other word from the list.
Additional note: when coding, always pay attention to the exact type and quoting in the answer. In Python code, the literal would appear as 'bridges' or "bridges" depending on the string delimeter used, but both denote the same string value. The key is that the value is the string bridges, not an integer or another type.
