Python - 如何在末尾生成带有新数字的变量列表 [英] Python - how to generate list of variables with new number at end

问题描述

我想要做的是找到一种更简洁的方法来创建彼此相似的空列表变量，但末尾的数字不同.

What I would like to do is find a more concise way of creating variables of empty lists that will be similar to each other, with the exception of different numbers at the end.

#For example:
var1 = []
var2 = []
var3 = []
var4 = []
#...
varN = []

#with the end goal of:
var_list = [var1,var2,var3,var4, ... varN]

推荐答案

使用 列表理解:

[[] for n in range(N)]

或者一个简单的 for 循环

or a simple for loop

empt_lists = []
for n in range(N):
    empt_lists.append([])

请注意，[[]]*N 不起作用，它将对所有项目使用相同的指针！！！

Note that [[]]*N does NOT work, it will use the same pointer for all the items!!!
