在Python 3中从嵌套的for循环输出值创建列表

Question

我嵌套了如下所示的for循环输出，并希望根据该输出值创建一个列表。请建议我如何实现此目标。

用于循环输出值：

Order_Numbers:
1234_90
3456_80
9876_70
2345_23

预期： 列表= [1234_90, 3456_80, 9876_70, 2345_23]

Answer 1

您可以将列表初始化为for循环外，并继续将值附加在“ for”循环内。伪代码如下，因为问题不是很清楚。

for .... (outer loops):
    order_number_list = [] #Initialize the list
    for.... (actual loop where the ordered number is created):
         order_number_list.append(number) #appends number to the created list
    print(order_number_list) #Doing this outside the innermost for loop is going to print expected output.
