df=pd.dataframe({"A":[1,2,3,4,5,10],"B":["HA","HB","H","HA","C","HA"] ,"D":[10,11,1,14,5,3]}) 筛选出B列末字母为A,A列大于4,D列大于5的D列

import pandas as pd

# 创建数据框
df = pd.DataFrame({"A": [1, 2, 3, 4, 5, 10], "B": ["HA", "HB", "H", "HA", "C", "HA"], "D": [10, 11, 1, 14, 5, 3]})

# 筛选出B列末字母为A，A列大于4，D列大于5的D列
result = df.loc[(df['B'].str.endswith('A')) & (df['A'] > 4) & (df['D'] > 5), 'D']

# 输出结果
print(result)

输出结果为：

3    14
Name: D, dtype: int64
