我是Python的新手,我的代码遇到了问题,我正在使用if in函数来做一个蔬菜水果商的计算器,当输入三个苹果正在购买时,总数正在生成为0英镑时应该是3.90英镑

total = 0


print "Welcome to the green grocers, what would you like?"
print "1. Apples"
print "2: Bananas"
print "3. Oranges"
print "4. Total"



fruit = raw_input("What would you like?")

if "1" in fruit:
   q = input("How many?")
   total + (q*1.3)
   fruit = raw_input("What would you like?")

if "2" in fruit:
   g = input("How many?")
   total + (g*1.5)
   fruit = raw_input("What would you like?")

if "3" in fruit:
   l = input("How many?")
   total = (l*1.6)
   fruit = …

我创建了一个表：

CREATE TABLE AIRLINE (
    airline_code        NUMBER(4) PRIMARY KEY NOT NULL,
    airline_name        VARCHAR(29) NOT NULL,
    airline_address1    VARCHAR(29) NOT NULL,
    airline_address2    VARCHAR(29),
    airline_postcode    VARCHAR(29),
    airline_city        VARCHAR(29) NOT NULL,
    airline_country     VARCHAR(29) NOT NULL
);

当我插入此插入语句时：

INSERT INTO AIRLINE (airline_code, airline_name, airline_address1, airline_address2, airline_postcode, airline_city, airline_country)
VALUES ("BA07", "British Airways PLC", "Waterside", "PO Box 365, Harmondsworth", "UB7 0GB", "London", "United Kingdom");

据我所知，有一个错误指向英国，说“此处不允许使用列”，据我所知，与将数据插入表中的列数相同。

我正在尝试按"完成"按钮来加载动作,最好是我对按钮的操作.

这是UITextField声明

let someTextField = UITextField()

尝试将目标添加到textField

someTextField.addTarget(self, action: "loginActionButton", forControlEvents: .EditingDidEndOnExit)
