Question

如果条件为假，如何返回第1行。

while True:
    food = int(input("food bill: "))
    if food <= 10:
        print("please write more than 10")
#If i put break statement here it does not go forward
    else:
        carbill = int(input("carbill: "))
    print("Total Montlhy expenditure is : " , grandtotal)

Answer 1

这就是你想要的-

while True:
    food = int(input("food bill: "))
    if food <= 10:
       print("please write more than 10")
       continue
    carbill = int(input("carbill: "))
    print("Total Montlhy expenditure is : " , food+carbill)

Answer 2

使用continue，它将返回到循环指令（适用于for）。
