当条件为真时，Pandas将数据帧拆分为多个

import pandas as pd

# 创建一个示例数据帧
data = {'Name': ['Alice', 'Bob', 'Charlie', 'David'],
        'Age': [25, 30, 35, 40],
        'Gender': ['Female', 'Male', 'Male', 'Male']}
df = pd.DataFrame(data)

# 拆分数据帧为多个子数据帧，条件为Age大于30
sub_dataframes = [group for _, group in df.groupby(df['Age'] > 30)]

# 打印拆分后的子数据帧
for sub_df in sub_dataframes:
    print(sub_df)

     Name  Age Gender
2  Charlie   35   Male
3    David   40   Male
