索引，字符串，列表

Question

浏览水果列表并在字符串“我将其添加到我们的产品”中打印每一个。该参数是“作物名称的列表（字符串），并没有返回值

测试用例

crops = [‘apple’, ‘orange’, ‘banana’, ‘strawberry’] 
daysWork(crops) 

I added this apple to our produce 
I added this orange to our produce 
I added this banana to our produce 
I added this strawberry to our produce 

我的代码：

def daysWork(crops): 
    for crop in crops: 
    produce = crops[n] 
    print 'I added this ' + str(produce) + ' to our produce' 

我得到的错误是”错误是：短语名称而不是全局找到”

为N的每个元素不是索引列表

Answer 1

？ Python的循环语句实际上是一个for-each语句，which differs from what you're used to in C or Java.for crop in crops引用crops中的每个元素与变量crop。

你想要什么，而不是为：

for crop in crops: 
    produce = crop
