python自动填充html数据需要数字，但数据类型为字符串

Question

我正在尝试使用python自动填充html表单数据。如果我在没有自动填充数据的情况下运行代码，网页加载就可以了。但是当我添加自动填充数据时，我得到：

TypeError: %d format: a number is required, not unicode

这是自动填充数据的代码：

class EditCarHandler(webapp2.RequestHandler):
template_variables = {}

def get(self):

    template = JINJA_ENVIRONMENT.get_template('/edit_cars.html')
    self.response.write(template.render(self.template_variables))

    carID = self.request.get('id')
    carData = Car.get_by_id(int(carID))

    colorArray = ['', '', '', '', '', '', '', '', '', '']
    for i in carData.color:
        if i == "red":
            colorArray[0] = " checked"
        elif i == "orange":
            colorArray[1] = " checked"
        elif i == "yellow":
            colorArray[2] = " checked"
        elif i == "green":
            colorArray[3] = " checked"
        elif i == "blue":
            colorArray[4] = " checked"
        elif i == "purple":
            colorArray[5] = " checked"
        elif i == "black":
            colorArray[6] = " checked"
        elif i == "white":
            colorArray[7] = " checked"
        elif i == "gray":
            colorArray[8] = " checked"
        elif i == "other":
            colorArray[9] = " checked"

    conditionArray = ['', '', '']
    if carData.condition == "new":
        conditionArray[0] = " checked"
    elif carData.condition == "used":
        conditionArray[1] = " checked"
    elif carData.condition == "damaged":
        conditionArray[2] = " checked"


    self.response.write("""

谢谢你的帮助

我明白了！错误出现在carData.color的逻辑中，而且单选按钮是“checked”而不是“selected”
