In Python

Write a program that does the following:

$1)$ Ask the user to $--$ Enter $\text{'}$b$\text{'}$ for bird or $\text{'}$m$\text{'}$ for mammal:

$2)$ Validate that input to allow only b$,$ B$,$ m$,$ or M

$3)$ Print "That is not a valid input" if an incorrect value was entered and have the user re$-$enter the input

$4)$ Upon successful input, display "You chose bird" or "You chose mammal" depending on their input.

Ex: If the input is:

Enter $\text{'}$b$\text{'}$ for bird or $\text{'}$m$\text{'}$ for mammal: B

the output is:

You chose bird
