如何按行数拆分数据帧

import pandas as pd

def split_dataframe_by_rows(df, rows_per_frame):
    split_frames = []
    current_frame = pd.DataFrame()
    
    for index, row in df.iterrows():
        current_frame = current_frame.append(row)
        
        if len(current_frame) == rows_per_frame:
            split_frames.append(current_frame)
            current_frame = pd.DataFrame()
    
    if len(current_frame) > 0:
        split_frames.append(current_frame)
    
    return split_frames

# 示例用法
data = {'Name': ['John', 'Emma', 'Mike', 'Emily', 'Daniel', 'Sophia'],
        'Age': [25, 28, 32, 27, 30, 35],
        'City': ['New York', 'London', 'Paris', 'Tokyo', 'Sydney', 'Berlin']}
df = pd.DataFrame(data)

split_frames = split_dataframe_by_rows(df, 2)
for frame in split_frames:
    print(frame)
    print('---')
