问题

我正在尝试练习格式化方法，如下所示：

Drinks = '{0},{1},{2}'
s = Drinks.format('coke', 'pepsi', 'miranda')
print(s)

然而，我遇到了这个错误：

> s = Drinks.format('coke', 'pepsi', 'miranda')
> AttributeError: 'str' object attribute 'format' is read-only

英文:

I'm trying to practice the format method as following:

Drinks = &#39;{0},{1},{2}&#39;
s = Drinks.format = (&#39;coke&#39;, &#39;pepsi&#39;, &#39;miranda&#39;)
print(s)

However I get this error:

> s = Drinks.format = ('coke', 'pepsi', 'miranda') AttributeError: 'str'
> object attribute 'format' is read-only

Drink.format 是一个函数，你不需要为它赋值，只需调用它（用括号而不是等号）：

s = Drink.format('coke', 'pepsi', 'miranda')

英文:

Drink.format is a function, you don't assign values to it, you simply call it (with parenthesis rather than an equal sign):

s = Drinks.format(&#39;coke&#39;, &#39;pepsi&#39;, &#39;miranda&#39;)
