创建具有名称的空列表列表

Question

我对 python 很陌生，正在寻找如何创建一个空列表的列表，其名称比下面显示的更有效

我想列出一些名字。

flattenlist_x1 = []
flattenlist_x2 = []
flattenlist_x3 = []
flattenlist_x4 = []
flattenlist_x5 = []
flattenlist_x6 = []
flattenlist_x7 = []
flattenlist_x8 = []
flattenlist_x9 = []
flattenlist_x10 = []
flattenlist_x11 = []
flattenlist_x12 = []

flattenlist_list = [flattenlist_x1, flattenlist_x2, flattenlist_x3, flattenlist_x4,
                    flattenlist_x5, flattenlist_x6, flattenlist_x7, flattenlist_x8,
                    flattenlist_x9, flattenlist_x10, flattenlist_x11, flattenlist_x12]

Answer 1

因为你希望它有名字，所以使用 dict 怎么样？

flattenlist_list = {}
for i in range(1,13):
    flattenlist_list['flattenlist_x'+str(i)]=[]
print(flattenlist_list)
