1. Write the word as **s t r a w b e r r y**. 2. The letter **r** appears in positions 3, 8, and 9. There are **3 r’s**.

The error means `users` is `undefined` when `UserList` renders, so calling `users.map(...)` fails. This often happens when the parent hasn’t passed the prop yet, such as while data is loading. One fix is to default `users` to an empty array: ```jsx function UserList({ users = [] }) { return ( <ul> {users.map(user => <li key={user.id}>{user.name}</li>)} </ul> ); } ``` Also check the parent component: it should pass an array, for example `<UserList users={users} />`. If the data is fetched asynchronously, initialize its state with an empty array: ```jsx const [users, setUsers] = useState([]); ``` The default parameter covers `undefined`, but not `null` or other non-array…

The function is straightforward, but a few changes would make its behavior clearer and safer: - **Avoid bare `except`:** It catches programming errors and interrupts as well as network failures. Catch expected exceptions instead. - **Don’t hide failures:** Returning `[]` for both a failed request and a valid empty response makes them indistinguishable. - **Retry selectively:** Retry connection failures, timeouts, and transient HTTP statuses—not every non-200 response. - **Avoid sleeping after the last attempt**, and use backoff between attempts. - **Move imports to module scope** and use descriptive variable names. - **Simplify the filtering** with a list comprehension. Check `is True` if t…
