如何通过添加其他表中的对象来操作python字典

dict1 = {'key1': 'value1'}
dict2 = {'key2': 'value2', 'key3': 'value3'}
dict1.update(dict2)
print(dict1)  # 输出：{'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}

dict1 = {'key1': 'value1'}
dict2 = {'key2': 'value2', 'key3': 'value3'}
dict1 = {**dict1, **dict2}
print(dict1)  # 输出：{'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}

dict1 = {'key1': 'value1'}
dict2 = {'key2': 'value2', 'key3': 'value3'}
for key, value in dict2.items():
    dict1[key] = value
print(dict1)  # 输出：{'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
