Python: Dictionary user$\_$ages contains four key$-$value pairs, each representing a student's name and age. Read a student name from input. Then, output the corresponding age from user$\_$ages. Finally, delete that pair from user$\_$ages.

Ex: If the input is Ada, then the output is:

$40$

Remaining pairs:

$\{\text{'}$Kim$\text{'}$: $61,$ 'Mai': $46,$ 'Ana': $32\}$
