如何分组数组并计算它们

# 定义需要分组和计算的数组
array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# 定义分组的依据，这里以奇偶数进行分组
def group_by_odd_even(num):
    if num % 2 == 0:
        return "偶数"
    else:
        return "奇数"

# 初始化一个空字典，用于保存分组和计算结果
result = {}

# 遍历数组，根据分组依据将元素放入对应的组中
for num in array:
    group = group_by_odd_even(num)
    if group in result:
        result[group].append(num)
    else:
        result[group] = [num]

# 对每个组进行计算，这里以求和为例
for group, nums in result.items():
    total = sum(nums)
    result[group] = total

# 打印计算结果
for group, total in result.items():
    print(f"{group}组的总和为：{total}")
