python的字典问题

Question

1. 编写一个程序，从键盘输入两个字典，将两个字典合并为一个字典，如果两个字典中分别有相同的键，需将对应的值相加后作为该键对应的新值。最后输出所有元素(键值对，中值最大的元素的键（若有多个这样的元素，只输出最大的那个键）。字典中键和值的数据类型都为整
   数。

Answer 1

dict1 = {}
dict2 = {}

print("第一个字典：")
while True:
    try:
        key, value = input().split()
        dict1[int(key)] = int(value)
    except:
        break

print("第二个字典：")
while True:
    try:
        key, value = input().split()
        dict2[int(key)] = int(value)
    except:
        break

merged_dict = {}
for key in dict1:
    if key in dict2:
        merged_dict[key] = dict1[key] + dict2[key]
    else:
        merged_dict[key] = dict1[key]
for key in dict2:
    if key not in merged_dict:
        merged_dict[key] = dict2[key]

print("合并后：", merged_dict)

max_value = max(merged_dict.values())
max_keys = [key for key in merged_dict if merged_dict[key] == max_value]
print("最大的键为：", max(max_keys))
