Improper deployment of the 'or' argument.

Question

Hi, all. I wrote a simple code that to practice this lesson and some previous ones but my deficiency is obvious. In the code (shown below), I employed multiple levels of branching. But, even though running the code does not return an error, it still does not accomplish my goal. I think I may be misusing the 'or' argument in line 15. Please, take a look at my code first before reading my question below.

My line 15 reads thus:

   elif A2 == fruit_choice2 or fruit_choice3:

I want to restrict this 'elif' to apply only when A2 (i.e the input for the choice of fruit in line 11) is either fruit_choice2 (i.e. "banana") or fruit_choice3 (i.e. "pear"). That is why I use the 'or' argument. If this code were written perfectly, only an input of "banana" and "pear" for A2 would trigger the printing of lines 16-18. In this ideal case, if I entered "carrot" for A2, python should print lines 20-22. Sadly, when I enter any input besides "apple", lines 16-18 are processed. This is not my intention. I believe the problem might be in how I employed the 'or' argument in line 15. How can I write it to accomplish my goal? How can I restrict the 'elif' to activate when only A2 is "banana" or "pear" only? Let me know if my question needs further clarification. And, if you understand it, please proffer a solution. Thank you.

# Write a code that encourages people to eat one apple each day but has a positive bias towards bananas and pears.

fruit_choice1 = "apple"
fruit_choice2 = "banana"
fruit_choice3 = "pear"


A0 = input("What is your name? ")
A1 = input("Do you eat a fruit serving each day, {}? (Y/N) ".format(A0))
if A1 == "Y":
    A2 = input("What fruit do you eat each day? (Enter a singular noun in lowercase, please) ")
    if A2 == fruit_choice1:
        print("Great choice, {}! Eating one {} a day is recommended.".format(A0,A2))
        print("Have a great {}-eating day today!".format(A2))
    elif A2 == fruit_choice2 or fruit_choice3:
      print("Good. Eating one {} a day is recommended, {}.".format(A2,A0))
      print("You can also eat one {} a day.".format(fruit_choice1))
      print("Have a great day, {}!".format(A0))
    else:
        print("Eating a fruit, including {} (if it is a fruit *wink*) is recommended for each day.".format(A2))
        print("You can also try eating a {} each day, {}.".format(fruit_choice1,A0))
        print("Have a great day today!")
elif A1 == "N":
    print("You should eat a fruit serving each day, {}.".format(A0))
    print("Why not try one {} today!".format(fruit_choice1))
    print("Have a great {}-eating day!".format(fruit_choice1))
else:
    print("I'm sorry I don't understand your response, {}. Please start all over.".format(A0))

So, you want to restrict line 15 of you're code to accept only "banana" or "pear"?. If that's the case, try this;

fruit_choice1 = "apple"
fruit_choice2 = "banana"
fruit_choice3 = "pear"


A0 = input("What is your name? ")
A1 = input("Do you eat a fruit serving each day, {}? (Y/N) ".format(A0))
if A1 == "Y":
    A2 = input("What fruit do you eat each day? (Enter a singular noun in lowercase, please) ")
    if A2 == fruit_choice1:
        print("Great choice, {}! Eating one {} a day is recommended.".format(A0,A2))
        print("Have a great {}-eating day today!".format(A2))
    elif A2 == fruit_choice2 or A2 == fruit_choice3:
        print("Good. Eating one {} a day is recommended, {}.".format(A2,A0))
        print("You can also eat one {} a day.".format(fruit_choice1))
        print("Have a great day, {}!".format(A0))
    else:
        print("Eating a fruit, including {} (if it is a fruit *wink*) is recommended for each day.".format(A2))
        print("You can also try eating a {} each day, {}.".format(fruit_choice1,A0))
        print("Have a great day today!")
elif A1 == "N":
    print("You should eat a fruit serving each day, {}.".format(A0))
    print("Why not try one {} today!".format(fruit_choice1))
    print("Have a great {}-eating day!".format(fruit_choice1))
else:
    print("I'm sorry I don't understand your response, {}. Please start all over.".format(A0))

Tage me again if this did not solve your problem.

boi , it worked. Thank you very much.

I see the difference between what we both did, but can you explain why mine was wrong, please? Thanks!
