如何将对象列表分组到字典中？

# 对象列表
objects = [
    {'name': 'Alice', 'age': 25, 'gender': 'female'},
    {'name': 'Bob', 'age': 30, 'gender': 'male'},
    {'name': 'Charlie', 'age': 35, 'gender': 'male'},
    {'name': 'David', 'age': 40, 'gender': 'male'},
    {'name': 'Eve', 'age': 45, 'gender': 'female'}
]

# 根据gender将对象列表分组到字典中
grouped_dict = {obj['gender']: [] for obj in objects}
for obj in objects:
    grouped_dict[obj['gender']].append(obj)

# 打印分组后的字典
for gender, group in grouped_dict.items():
    print(gender, group)

female [{'name': 'Alice', 'age': 25, 'gender': 'female'}, {'name': 'Eve', 'age': 45, 'gender': 'female'}]
male [{'name': 'Bob', 'age': 30, 'gender': 'male'}, {'name': 'Charlie', 'age': 35, 'gender': 'male'}, {'name': 'David', 'age': 40, 'gender': 'male'}]
