Otherwise, we will put the key-value pairs in the new dictionary. For instance, suppose that we have the following dictionary. myDict = { "Article": "Remove One or Multiple Keys From a Dictionary in Python", "Topic": "Python Dictionary", "Keyword": "Remove key from dictionary in ...
if "age" in my_dict: my_dict.remove("age") else: print("键不存在") #打印处理后的字典 print(my_dict) ``` 通过先检查键是否存在,我们可以避免出现KeyError异常。 总结一下,Python中字典的remove方法可用于删除指定键的键值对。我们可以使用该方法来对字典进行动态修改和管理,使其更符合我们的需求。记...
1.字典(dict) 2.元组(tuple) 3.文件 4.数据类型总结 这节课我们学习Python中其他的数据类型,首先字典表(dict)它是通过键-值对的形式存储数据的一种格式,在其他的编程语言中也被称为hash表,在字典表中元素没有下标也没有先后顺序,仅依靠它的键值对应。之后学习了元组(tuple),它是不可原位改变的数据类型。最...
