如何解决使用 not in 和 in - Python？

开发过程中遇到使用 not in 和 in - Python的问题如何解决？下面主要结合日常开发的经验，给出你关于使用 not in 和 in - Python的解决方法建议，希望对你解决使用 not in 和 in - Python有所启发或帮助；

small_pizza = 15
medium_pizza = 20
large_pizza = 25
pepperoni_small_pizza = 2
pepperoni_med_or_large_pizza = 3
extra_cheese = 1
    
print("Welcome to Pizza Palace")
print("Thank you for choosing us.")
pizza_size = input("Which size pizza would you like 1) small 2) Medium 3) Large :")
if pizza_size == "1" or "small":
    pepperoni = input(f"Would you like to add pepperoni for ${pepperoni_small_pizza} :")
    cheese = input(f"Would you like to add extra cheese for ${extra_cheesE} :")
    if pepperoni and cheese in ["Y","y","Yes","yes","YES"]:
        bill = small_pizza + pepperoni_small_pizza + extra_cheese
        print(f"Thank you,your @R_102_10586@l bill is ${Bill}.")
    elif pepperoni in ["Y","YES"] and cheese in ["N","n","No","NO","no"]:
        bill = small_pizza + pepperoni_small_pizza
        print(f"Your @R_102_10586@l bill is ${Bill}.")
    elif pepperoni in ["N","no"] and cheese in ["Y","YES"]:
        bill = small_pizza + extra_cheese
        print(f"Your @R_102_10586@l bill is ${Bill}.")
    elif cheese and pepperoni in ["N","no"]:
        bill = small_pizza
        print(f"Your bill is ${Bill}.")

当我尝试使用以下输入运行此代码时：
i/p：1 年 y

o/p：
Welcome to Pizza Palace Thank you for choosing us.  
Which size pizza would you like 1) >small 2) Medium 3) Large :1   
Would you like to add pepperoni for $2 :y   
Would you like to add extra cheese for $1 :y   
Thank you,your @R_102_10586@l bill is $18.

  
@H_675_5@

i/p: 1 y n

o/p：
Welcome to Pizza Palace Thank you for choosing us. 
 Which size pizza would you like 1) small 2) Medium 3) Large :1 
 Would you like to add pepperoni for $2 :y 
 Would you like to add extra cheese for $1 :n 
 Your @R_102_10586@l bill is $17.
  
@H_675_5@

i/p: 1 n n

o/p：
Welcome to Pizza Palace Thank you for choosing us. 
Which size pizza would you like 1) >small 2) Medium 3) Large :1 
Would you like to add pepperoni for $2 :n 
Would you like to add extra cheese for$1 :n 
Your bill is $15.


 
@H_675_5@

但是使用 i/p：
1 年 y

o/p:
Welcome to Pizza Palace
Thank you for choosing us.
Which size pizza would you like 1) small 2) Medium 3) Large :1
Would you like to add pepperoni for $2 :n
Would you like to add extra cheese for $1 :y
Thank you,your @R_102_10586@l bill is $18.
@H_675_5@
为什么会这样？
任何人都可以帮我解决这个问题吗？

当我输入意大利辣香肠：n 和奶酪：y

第三个 if 案例应该接管，但为什么第一个 if 案例是意大利辣香肠和奶酪
y 是否正在执行。

当使用“and”时，只有当意大利辣香肠和
奶酪是真的。
为什么即使一个陈述为假，条件也成立
执行了吗？
