补充以下代码以实现每个空之前的注释中描述的功能: words_dict={"fruit":"水果","car":"卡车","bottle":"瓶子","coffee":"咖啡","banana":"香蕉"} added_dict={"apple":"苹果","dumpling":"饺子","mooncake":"月饼"} #返回一个字典的浅复制并将其赋值给copy_words_dict 1 print(copy_words_dict) print(words_dict) #修改字典copy_words_dict键"car"及与该键关联的值为"汽车" 2 print(words_dict) print(copy_words_dict) #删除字典copy_words_dict的键"bottle"及其值 3 print(words_dict) #返回字典copy_words_dict中的所有值并保存在chinese_words中 4 print(chinese_words)
