Question

侧面有两个星星的线不起作用，显示语法错误 我真的很沮丧，请帮助，应该是这样的行： if food ==（“ 1”）：

#Python tutorials
import sys# allows the exit function
import time

#Menu
print("************MAIN MENU**************")
time.sleep(1)
choice = input("""
                      A: Add an item
                      B: Delete an Item
                      C : Checkout
                      Q: Quit/Log Out

                      Please enter your choice: """)


#Adding
if choice == "A" or choice =="a":
    print("Choose from following numbers, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12")
    food = int(input("1,12")
        **if food == ("1"):**
               print("You want to add the All day (large) Breakfast")
               time.sleep(0.5)
               print("Add another item?")
               time.sleep (0.5)
               print("To add another item just type the number")
        elif food == ("2"):
            print ("You want to add the All day (small) Breakfast")
            time.sleep(0.5)
            print("Add another item?")
            time.sleep (0.5)
            print("To add another item just type the number") 
elif choice == "B" or choice =="b":
    print("Choose from following numbers, 1, 2, 3, 4, 5,6 ,7, 8, 9, 10, 11, 12")
elif choice=="C" or choice=="c":
    print ("Are you sure?")
elif choice=="Q" or choice=="q":
    print ("your mom")```

您应该小心括号和缩进。仅当您写:时，才应向右滑动。并且您应该关闭每个括号。另外，您的食物变量是int，而不是str。如果比较int和str，则为False。这是有效的代码：

if choice == "A" or choice =="a":
    print("Choose from following numbers, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12")
    food = int(input("1,12"))
    if food == 1:
           print("You want to add the All day (large) Breakfast")
           time.sleep(0.5)
           print("Add another item?")
           time.sleep (0.5)
           print("To add another item just type the number")
    elif food == 2:
        print ("You want to add the All day (small) Breakfast")
        time.sleep(0.5)
        print("Add another item?")
        time.sleep (0.5)
        print("To add another item just type the number") 
elif choice == "B" or choice =="b":
    print("Choose from following numbers, 1, 2, 3, 4, 5,6 ,7, 8, 9, 10, 11, 12")
elif choice=="C" or choice=="c":
    print ("Are you sure?")
elif choice=="Q" or choice=="q":
    print ("your mom")
