Type in the code below to display a menu system and perform a task. Create a function called

$$do$\_$something$$ that simply displays what was done. Be sure to build in an error checking mechanism

that warns the user of an invalid choice. Hint: your function will incorporate an IF test to determine

what is output. $(7$ points$)$

def main$()$:

print$\_$menu$()$

choice $=$ int$($input$("$Please enter choice: $"))$

do$\_$something$($choice$)$ #function call

def print$\_$menu$()$:

print$("1.$ Create username"$)$

print$("2.$ Delete user"$)$

print$("3.$ Change address"$)$

print$("0.$ Exit program"$)$

main$()$

$1.$ A username was created

$2.$ A user was deleted

$3.$ An address was changed

$0.$ Exit
