In Python, what is the output of `type((42,))`?
Answer and explanation
Correct answer: C. `<class 'tuple'>`
- Step 1: In Python, parentheses with a single element followed by a trailing comma define a single-element tuple.
- Step 2: Without the comma, `(42)` is treated as a parenthesized integer, but with the comma `(42,)`, it is a tuple.
Answer
`<class 'tuple'>`.
Why not the others: '`<class 'int'>`' is the type of `(42)` without the trailing comma; '`<class 'list'>`' uses square brackets `[42]`; '`<class 'set'>`' uses curly braces `{42}`.
