使一个python for循环返回一个整数列表

Question

我有像这样的循环python

for i in view_overall_isp_ratings:
        #the int and the round is just for casting the values returned
        me = (int(round(i.avg_of_ratings)))
        print(me)

and this prints intergers like this 1
                                    1
                                    1
                                    1
                                    4

我想要什么

for it to produce a list like this 
    [ 1 ,1 ,1 ,1 ,4]

尝试玩[]，但至少我能得到的是

 [1]
 [1]
 [1]
 [1]
 [4]

任何人都可以提供协助

Answer 1

你需要创建一个列表（在循环之外！）并在每次循环迭代中追加它：

lst = []
for i in view_overall_isp_ratings:
    #the int and the round is just for casting the values returned
    lst.append(int(round(i.avg_of_ratings)))

print(lst)

或者，以更清洁的方式，您可以使用列表理解：

print([int(round(i.avg_of_ratings)) for i in view_overall_isp_ratings])
