如何在pandas中只获取"index value dtype“的值？

import pandas as pd

# 创建一个示例DataFrame
data = {'A': [1, 2, 3], 'B': [4, 5, 6]}
df = pd.DataFrame(data)

# 使用.info()方法获取"index value dtype"的值
info = df.info()

# 打印结果
print(info)

<class 'pandas.core.frame.DataFrame'>
RangeIndex: 3 entries, 0 to 2
Data columns (total 2 columns):
 #   Column  Non-Null Count  Dtype
---  ------  --------------  -----
 0   A       3 non-null      int64
 1   B       3 non-null      int64
dtypes: int64(2)
