如何在字典Python中添加列表作为值

Question

I'm trying to create a dictionary where keys are strings and values are lists. 我正在尝试创建一个字典，其中键是字符串，值是列表。 Something like that 像这样

l1 = ['a', 'b', 'c']

and I want to add lists similar to that one in every iteration in a for loop. 我想在for循环的每次迭代中添加与该列表相似的列表。

I've tried this 我已经试过了

dicc['first'].append(l1)

The exit should be something like that: 出口应该是这样的：

dicc={'first': ['a', 'b', 'c']}

I always get the same error: list indices must be integers or slices, not str 我总是遇到相同的错误： list indices must be integers or slices, not str

How can i do it? 我该怎么做？

在这种情况下，您必须为字典中的键分配一个列表给您，在这种情况下：

dicc['first'] = l1
