我正在为游戏编程一个机器人。我想在变量名称中使用变量。我写了一个简化的代码来检查我的函数，它有效。然后将我的代码放入真正的机器人中，它只是不起作用。 代码有一个显示玩家的类。机器人正在从另一个文件中导入。这正在工作，我已经尝试过了。
我在互联网上搜索了很多，对我来说最好的解决方案是exec((。但如果有更好的我会接受它？
this is the simple code
p1_l=[1,2,3,4,5]
p2_l=[6,7,8,9,10]
p3_l=[11,12,13,14,15]
p4_l=[16,17,18,19,20]
#these are the known lists
a="p1"
#a is deciding if we are going to work with list 1,2,3 or 4
#the value of a is random
b=str(a)+"_l"
#b is now "list_1"
#now i have an function foo()
def foo(a):
return a
#this functions is only an simple example
#now i want to use my b in this function
#i only know one possible way with exec()
exec("r=foo({})".format(b))
print(r)
#but this is not working
那是真正的代码

The parameters to this function are:
* `hand`: A list of card strings that are the card(s) in your hand.
* `is_start_of_round`: A Boolean that indicates whether or not the `play` function is being asked to make the first play of a round.
* `play_to_beat`: The current best play of the trick. If no such play exists (you are the first play in the trick), this will be an empty list.
* `round_history`: A list of *trick_history* entries.
A *trick_history* entry is a list of *trick_play* entries.
Each *trick_play* entry is a `(player_no, play)` 2-tuple, where `player_no` is an integer between 0 and 3 (inclusive) indicating which player made the play, and `play` is the play that said player made, which will be a list of card strings.
* `player_no`: An integer between 0 and 3 (inclusive) indicating which player number you are in the game.
* `hand_sizes`: A 4-tuple of integers representing the number of cards each player has in their hand, in player number order.
* `scores`: A 4-tuple of integers representing the score of each player at the start of this round, in player number order.
* `round_no`: An integer between 0 and 9 (inclusive) indicating which round number is currently being played.
This function should return an empty list (`[]`) to indicate a pass (see "Playing a Round"), or a list of card strings, indicating that you want to play these cards to the table as a valid play.

问题在于在实际代码中，我的变量"r"没有定义。所以 exec(( 函数没有将"r"定义为p1_hand之一。列表。
我希望这是可以理解的。 谢谢

对于测试代码中的示例，我将改用列表字典：
my_dict = {"p1": [elem1, elem2], "p2":[elem3, elem4], ...}
要访问它，您可以执行以下操作：
player = "p1"
player_list = my_dict[player]
