如果两个键都在两个独立的字典中，如何获取字典键和值？

dict1 = {'key1': 'value1', 'key2': 'value2', ...}
dict2 = {'key3': 'value3', 'key4': 'value4', ...}

keys1 = dict1.keys()  # 获取dict1中的所有键
keys2 = dict2.keys()  # 获取dict2中的所有键

values1 = dict1.values()  # 获取dict1中的所有值
values2 = dict2.values()  # 获取dict2中的所有值

for key in keys1:
    value = dict1[key]
    print("键: ", key)
    print("值: ", value)

for key in keys2:
    value = dict2[key]
    print("键: ", key)
    print("值: ", value)
