我有多个包含名称和计数的元组列表,我希望将它们的名称与它们各自的计数之和合并。例如,我有:
l1 = [('House', 3),('Backyard', 2),('Frontyard', 4)]
l2 = [('House', 10),('street', 7),('Frontyard', 4)]
l3 = [('Backyard', 10),('street', 7),('Frontyard', 4)]
我想得到:
result : [('house', 13),('Backyard', 12), ('street', 14), ('Frontyard', 12)]
答案 0 :(得分:0)
只需使用一个字典进行累计......
result = {}
for L in l1, l2, l3:
for key, value in L:
result[key] = result.get(key, 0) + value
# convert to a list
result = list(result.items())
