分组时获取两列字典列表

data = [
    {'name': 'Alice', 'age': 25, 'gender': 'female'},
    {'name': 'Bob', 'age': 30, 'gender': 'male'},
    {'name': 'Charlie', 'age': 35, 'gender': 'male'},
    {'name': 'David', 'age': 28, 'gender': 'male'},
    {'name': 'Eve', 'age': 27, 'gender': 'female'},
    {'name': 'Frank', 'age': 32, 'gender': 'male'}
]

import itertools

# 按照性别进行分组
groups = itertools.groupby(data, key=lambda x: x['gender'])

for key, group in groups:
    # 获取每个分组中的姓名和年龄
    names = [item['name'] for item in group]
    ages = [item['age'] for item in group]
    print(f"Group: {key}")
    print(f"Names: {names}")
    print(f"Ages: {ages}")
