如何计算列表列表中的项目

my_list = [1, 2, 3, 4, 5]
total = 0

for item in my_list:
    total += item

print("列表中项目的总和为：", total)

my_list = [1, 2, 3, 4, 5]
total = 0

for item in my_list:
    total += item

average = total / len(my_list)

print("列表中项目的平均值为：", average)

my_list = [1, 2, 3, 4, 5]
max_value = my_list[0]
min_value = my_list[0]

for item in my_list:
    if item > max_value:
        max_value = item
    if item < min_value:
        min_value = item

print("列表中的最大值为：", max_value)
print("列表中的最小值为：", min_value)

my_list = [1, 2, 3, 2, 4, 1, 5, 2]
frequency = {}

for item in my_list:
    if item in frequency:
        frequency[item] += 1
    else:
        frequency[item] = 1

print("列表中每个项目的频次：", frequency)
