How to store variables in arraylist in python
提问by Mahakaal
I want to have something like
我想要类似的东西
var1 = ('a','b','c')
var2 = ('a1','b1','c1')
var3 = ('a2','b2','c2')
var4 = ('a3','b4','c5')
var5 = ('a6','b6','c6')
How can i have all those in one variable var
我如何将所有这些都放在一个变量 var 中
I have a loop which will be saving each array but i want to have only one variable
我有一个循环将保存每个数组，但我只想有一个变量
采纳答案by phihag
var = [var1, var2, var3, ('a3', 'b4', 'c5'), var5]
You could also copy variin a loop, but that's very bad programming practice. Basically, you should construct a list upfront and not later from variable names. If you must do it, here's how:
您也可以在循环中复制 var i，但这是非常糟糕的编程习惯。基本上，您应该预先构建一个列表，而不是稍后从变量名称构建。如果您必须这样做，请执行以下操作：
var = [locals()['var' + str(i)] for i in range(6)]
This is the longer form of:
这是更长的形式：
var = []
for i in range(6):
var.append(locals()['var' + str(i)])
