Contact Book From Input

Build a contact book from the input, then answer one lookup. Input: the first line is a whole number n; then n pairs of lines follow, a name line and then that person's number line; the final line is a name to look up. Read everything with a bare input(), no prompts, using range(n) for the pairs. Store each pair in a dict with the name as the key. For the lookup use in to check the key first: print the number if the name was added, otherwise print <name> not found. Output: one line.
