如何使用If获得想要的输出？

嗨，我是python的新手，我想做一个内向/外向测验，当我尝试采用外向选项时，它不会在任何外向答案上+1，相反，它只会在内向+1每次都回答。那么我需要做什么才能使它正常工作？

extro = 0
intro = 0

print("1.------------------? : ")
d1a = input("A) ------------------.\n"
            "B) ------------------.\n"
            "[A/B]? : ")
if d1a == "B" or "b":
    intro = intro + 1
elif d1a == "A" or "a":
    extro = extro + 1


print("2.------------------? : ")
d2a = input("A) ------------------.\n"
            "B) ------------------.\n"
            "[A/B]? : ")
if d2a == "B" or "b":
    intro = intro + 1
elif d2a == "A" or "a":
    extro = extro + 1


print("3.------------------? : ")
d3a = input("A) ------------------.\n"
            "B) ------------------.\n"
            "[A/B]? : ")
if d3a == "B" or "b":
    intro = intro + 1
elif d3a == "A" or "a":
    extro = extro + 1



print("4.------------------? : ")
d4a = input("A) ------------------.\n"
            "B) ------------------.\n"
            "[A/B]? : ")
if d4a == "B" or "b":
    intro = intro + 1
elif d4a == "A" or "a":
    extro = extro + 1


print("5.------------------? : ")
d5a = input("A) ------------------.\n"
            "B) ------------------.\n"
            "[A/B]? : ")
if d5a == "B" or "b":
    intro = intro + 1
elif d5a == "A" or "a":
    extro = extro + 1


print("6.------------------? : ")
d6a = input("A) ------------------.\n"
            "B) ------------------.\n"
            "[A/B]? : ")
if d6a == "B" or "b":
    intro = intro + 1
elif d6a == "A" or "a":
    extro = extro + 1


if intro >= int(5):
    print ("you are an introvert")    

if extro >= int(5):
    print ("you are an extrovert")

print("you are an ambivert")



print("Thank you.")
