python - 有没有办法从多个字典中访问具有相同名称的键？

Question

我有多个具有可预测名称的词典。每个字典包含 3 个元素。我如何才能从每个字典中提取特定键并找到总值？

player_A = {
   "kills": 15
   "death": 3
   "kda": 5
}

player_B = {
   "kills": 20
   "death": 4
   "kda": 5
}
:
player_ZA = {
   "kills": 35
   "death": 7
   "kda": 5
}

假设我想找出所有玩家的总击杀数。我应该如何访问字典中名为“kill”的所有键并找到这些键的总和？

即。预期输出类似于:

sum(15 + 20 + ... + 35)

Answer 1

player_a = {"kills": 15, "death": 3, "kda": 5}
player_b = {"kills": 20, "death": 4, "kda": 5}
player_c = {"kills": 35, "death": 7, "kda": 5}

players = [player_a, player_b, player_c]

total_kills = sum(player["kills"] for player in players)
