python 二维表格有姓名性别 分性别统计姓

这里提供一种实现方式:

# 二维表格数据
data = [
    ["张三", "男"],
    ["李四", "男"],
    ["王五", "女"],
    ["赵六", "女"],
    ["钱七", "男"],
    ["孙八", "女"],
    ["周九", "男"],
    ["吴十", "女"],
]

# 姓氏分类
male_names = []  # 男性姓名列表
female_names = []  # 女性姓名列表

for row in data:
    name, gender = row
    if gender == "男":
        male_names.append(name)
    elif gender == "女":
        female_names.append(name)

# 统计姓氏数量
def count_surname(names):
    surname_count = {}
    for name in names:
        surname = name[0]
        if surname in surname_count:
            surname_count[surname] += 1
        else:
            surname_count[surname] = 1
    return surname_count

male_surname_count = count_surname(male_names)  # 男性姓氏数量
female_surname_count = count_surname(female_names)  # 女性姓氏数量

# 打印结果
print("男性姓氏:")
for surname, count in male_surname_count.items():
    print(surname, count)

print("女性姓氏:")
for surname, count in female_surname_count.items():
    print(surname, count)

输出结果:

男性姓氏:
张 1
李 1
钱 1
周 1
女性姓氏:
王 1
赵 1
孙 1
吴 1
