Python Pandas - Get location for a label or a tuple of labels in a MultiIndex
To get location for a label or a tuple of labels in a MultiIndex, use the MultiIndex.get_loc() method in Pandas.
At first, import the required libraries −
import pandas as pd
MultiIndex is a multi-level, or hierarchical, index object for pandas objects −
multiIndex = pd.MultiIndex.from_arrays([list('pqrrss'), list('stuvwx')])
Display the MultiIndex −
print("The MultiIndex...\n",multiIndex)Get the location −
print("\nGet the locations in MultiIndex...\n",multiIndex.get_loc('s'))
Example
Following is the code −
import pandas as pd
# MultiIndex is a multi-level, or hierarchical, index object for pandas objects
multiIndex = pd.MultiIndex.from_arrays([list('pqrrss'), list('stuvwx')])
# display the MultiIndex
print("The MultiIndex...\n",multiIndex)
# get the levels in MultiIndex
print("\nThe levels in MultiIndex...\n",multiIndex.levels)
# Get the location
print("\nGet the locations in MultiIndex...\n",multiIndex.get_loc('s'))Output
This will produce the following output −
The MultiIndex...
MultiIndex([('p', 's'),
('q', 't'),
('r', 'u'),
('r', 'v'),
('s', 'w'),
('s', 'x')],
)
The levels in MultiIndex...
[['p', 'q', 'r', 's'], ['s', 't', 'u', 'v', 'w', 'x']]
Get the locations in MultiIndex...
