Class Dict类型是指Python中的字典类型,它是一种无序的键值对集合,可以通过键来访问对应的值。访问Class Dict类型中的数据有以下几种方式: 1. 使用方括号([])访问:可以通过...
dict_keys([1, 2]) dict_values(['hello', 'world']) dict_items([(1, 'hello'), (2, 'world')]) """ 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
print(my_dict.get('name', 'Not found')) #输出: Not found 在上面的例子中,我们使用del关键字删除了键'name'对应的键值对,并通过get()方法来验证该键对应的值确实已经被删除。 除了基本的创建、访问、修改和删除操作外,字典还有很多其他实用的方法。例如,我们可以使用keys()方法来获取字典中所有的键,values...
The names of the characters are the keys of the dictionary and the names of the actors are the values of the dictionary. This dictionary (OthelloDict) is contained in a class (OthelloCast) that is derived from a List<T> class. The constructor for the OthelloCast object populates its ...
同时dict.items遍历有点类似enumerate(list)的双变量遍历,不过dict是只有key、value,而list是只有index、value for key in dict.keys() 遍历字典的键可以通过for key in dict.keys()或者 `for key in dict:进行遍历 两种遍历方式得到的结果是相同的
