python中的随机列表选择 [英] Random List choices in python

问题描述

是否可以将变量传递给列表的choice()函数.我有一堆列表，我想从一个列表中随机选择，然后使用返回的字符串从具有该字符串名称的列表中进行选择.

Is there a way to pass a variable to the choice() function for a list. I have a bunch of lists and I want to randomly select from one list and then use the string that is returned to select from a list that has that string name.

A = ['1','2','3']

print choice (A) - this gets me a random choice from the list

但是我想将选择存储为变量，并使用它来调用另一个列表

but I want to to store the choice as a variable and use it to call another list

A = ['1','2','3']
1 = ['A','B','C']

Var1 = choice (A)

print choice (Var1) *** this is my problem, how do I pass a variable to the choice function

感谢您的帮助！

推荐答案

在Python中，您可以使用引用.

In Python, you can do this using references.

A = [1, 2, 3]
B = [4, 5, 6]
C = [7, 8, 9]
MasterList = [A, B, C]

whichList = choice(MasterList)
print choice(whichList)

请注意，A, B, C是先前分配的变量的名称，而不是带引号的字符串.如果您发现自己使用带引号的名称来引用变量，通常可以使用一种更好的方法来完成您要尝试执行的操作.

Note that A, B, C are names of previously assigned variables, instead of quoted strings. If you ever find yourself using quoted names to refer to variables, there's usually a better way to do whatever you're trying to do.
