如何在不创建新字典的情况下更新字典？

original_dict = {'key1': 'value1', 'key2': 'value2'}
new_dict = {'key2': 'new value', 'key3': 'value3'}

original_dict.update(new_dict)
print(original_dict)

{'key1': 'value1', 'key2': 'new value', 'key3': 'value3'}

original_dict = {'key1': 'value1', 'key2': 'value2'}

original_dict.update(key2='new value', key3='value3')
print(original_dict)

{'key1': 'value1', 'key2': 'new value', 'key3': 'value3'}

original_dict = {'key1': 'value1', 'key2': 'value2'}
items = [('key2', 'new value'), ('key3', 'value3')]

original_dict.update(items)
print(original_dict)

{'key1': 'value1', 'key2': 'new value', 'key3': 'value3'}
