如何从组1中选择X行而从group2中选择Y行对pandas数据帧进行采样

import pandas as pd

# 创建组1的数据帧
group1 = pd.DataFrame({'A': [1, 2, 3, 4, 5],
                       'B': ['a', 'b', 'c', 'd', 'e']})

# 创建组2的数据帧
group2 = pd.DataFrame({'A': [6, 7, 8, 9, 10],
                       'B': ['f', 'g', 'h', 'i', 'j']})

# 将两个组合并
combined = pd.concat([group1, group2])

# 从组1中选择X行，从组2中选择Y行进行采样
sampled_data = combined.sample(n=X, weights=[1 if i < len(group1) else 0 for i in range(len(combined))], replace=False)

# 打印采样结果
print(sampled_data)
