Python中有没有一种方法可以获取一个字符串并找到它所关联的列表？

Question

l1 = ["a","b","c"]
l2 = ["d","e","f"]

var1 = input("What list do you want to use? (l1 or l2)" 

print (var1)
output: l1 

如果用户在l1中键入，那么输出将是：["a","b","c"]，我该如何设置

我发现的最接近的例子是：

x='buffalo'    
exec("%s = %d" % (x,2))

Answer 1

if var1 == 'I1':
  print(I1)
elif var1 == 'I2':
  print(I2)

这只是一个基本的if/else
