How to manipulate MultiIndex pandas series?

I need to extract data from multiple sites.
Firstly read file
dfs = pd.read_excel('Consumption Report.xlsx', sheet_name='Elec Monthly Cons', header=[0,1], index_col=[0,1])
My Jupyter image
What I have tried so far:
dfs.iloc[0]
Output:

I need to extract data from multiple sites.
Firstly read file
dfs = pd.read_excel('Consumption Report.xlsx', sheet_name='Elec Monthly Cons', header=[0,1], index_col=[0,1])
My Jupyter image
What I have tried so far:
dfs.iloc[0]
Output:

1 2015-02-10 7 X Y

import pandas as pd

df
Output:
ColumnA ColumnB
IndexID IndexDateTime IndexAttribute
1 2015-02-05 8 A B
7 C D
2015-02-10 7 X Y
The values of the last column(ColumnB) can be accessed via df.loc[:, "ColumnB"].values, or df.loc[:, "ColumnB"]. See: https://pandas.pydata.org/pandas-docs/stable/indexing.html
IndexID IndexDateTime IndexAttribute
1 2015-02-05 8 B
7 D
2015-02-10 7 Y
Name: ColumnB, dtype: object
The first argument to df.loc[rows, columns] or df.iloc[rows, columns] refers to the rows or columns to slice, respectively.
To get the values from the index:
df.index.get_level_values(level=-1)
df.index.get_level_values(level="IndexAttribute")
Both return:
Int64Index([8, 7, 7], dtype='int64', name='IndexAttribute')
Is that what you had in mind?

df.index.get_level_values(level="IndexAttribute")
Both return:
Int64Index([8, 7, 7], dtype='int64', name='IndexAttribute')
Is that what you had in mind?

Given a dataframe:
"""
IndexID IndexDateTime IndexAttribute ColumnA ColumnB
1 2015-02-05 8 A B
1 2015-02-05 7 C D
1 2015-02-10 7 X Y
"""
import pandas as pd
import numpy as np
df = pd.read_clipboard(parse_dates=["IndexDateTime"]).set_index(["IndexID", "IndexDateTime", "IndexAttribute"])
df
Output:
ColumnA ColumnB
IndexID IndexDateTime IndexAttribute
1 2015-02-05 8 A B
7 C D
2015-02-10 7 X Y
The values of the last column(ColumnB) can be accessed via df.loc[:, "ColumnB"].values, or df.loc[:, "ColumnB"]. See: https://pandas.pydata.org/pandas-docs/stable/indexing.html
IndexID IndexDateTime IndexAttribute
1 2015-02-05 8 B
7 D
2015-02-10 7 Y
Name: ColumnB, dtype: object
The first argument to df.loc[rows, columns] or df.iloc[rows, columns] refers to the rows or columns to slice, respectively.
To get the values from the index:
df.index.get_level_values(level=-1)
df.index.get_level_values(level="IndexAttribute")
Both return:
Int64Index([8, 7, 7], dtype='int64', name='IndexAttribute')
Is that what you had in mind?
