Python Pandas - Return vector of label values for requested level in a MultiIndex
To return vector of label values for requested level in a MultiIndex, use the multiIndex.get_level_values() method. Set the level name as an argument.
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('strvwx')],names=['One', 'Two'])
Display the MultiIndex −
print("The MultiIndex...\n",multiIndex)
Get the levels in MultiIndex −
print("\nThe levels in MultiIndex...\n",multiIndex.levels)
Get level values at level 0 −
print("\nLevel values...\n",multiIndex.get_level_values(0))
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('strvwx')],names=['One', 'Two']) # display the MultiIndex print("The MultiIndex...\n",multiIndex) # get the levels in MultiIndex print("\nThe levels in MultiIndex...\n",multiIndex.levels) # get level values at level 0 print("\nLevel values...\n",multiIndex.get_level_values(0)) # get level values with level name "Two" print("\nLevel values...\n",multiIndex.get_level_values("Two"))
Output
This will produce the following output −
The MultiIndex... MultiIndex([('p', 's'), ('q', 't'), ('r', 'r'), ('r', 'v'), ('s', 'w'), ('s', 'x')], names=['One', 'Two']) The levels in MultiIndex... [['p', 'q', 'r', 's'], ['r', 's', 't', 'v', 'w', 'x']] Level values... Index(['p', 'q', 'r', 'r', 's', 's'], dtype='object', name='One') Level values... Index(['s', 't', 'r', 'v', 'w', 'x'], dtype='object', name='Two')
