response = input("Do you like kittens? ")


if response.lower() == "yes" :
    print("Meow")

elif response.lower() == "no" :
    print("Me neither.")

else :
    print("Ok...")

convert the response so it's in the same case as your test word (in this case, we're using lowercase)

indentation matters!
use the tab key to indent

elif means "or else if..."
you can have as many
of these as you want!

else covers all other possible responses

name = input("What is your name? ")




print("Hi, " + name.capitalize())

this is what the program will say to the user
