在对字典的值进行求和时,可以使用sum函数结合字典的values()方法来实现。values()方法返回一个包含字典中所有值的可迭代对象,然后将该可迭代对象作为sum函数的参数传入即可。 下面是一个示例代码: 代码语言:txt 复制 my_dict = {'a': 1, 'b': 2, 'c': 3} result = sum(my_dict.values()) print(resu...
在Python中,嵌套字典(Nested Dictionary)是指一个字典中包含另一个或多个字典作为值。要计算嵌套字典中所有值的总和,可以使用递归(Recursion)的方法来实现。 下面是一个示例的嵌套字典: 代码语言:txt 复制 nested_dict = { 'dict1': {'key1': 1, 'key2': 2, 'key3': 3}, 'dict2': {'key4': 4...

sum()은 list, tuple, dictionary의 합을 리턴하는 함수입니다. 숫자만 가능하며, 숫자가 아닌 객체가 있을 때 TypeError가 발생합니다. sum(iterable) - iterable의 합 리턴 , sum(ite
python 中,序列表示索引为非负整数的有序对象集合,包括字符串,列表和元组。 求和函数sum() sum的函数原型为 sum(s[,start]) 1. 其中 iterable 是可迭代对象,如:列表(list)、元组(tuple)、集合(set)、字典(dictionary)。 start 是指定相加的参数,如果没有设置这个值,默认为0 ...
sum_dict = sum(dict1.values()) print(sum_dict) #输出 6 (三)计算集合中元素的和: 例如: set1 = {1,2,3,4,5} sum_set = sum(set1) print(sum_set) #输出 15 (四)计算生成器中元素的和: 例如: generator = (i for i in range(1, 6)) sum_generator = sum(generator) print(sum_ge...
