To set only a single new specific level using the level name in a MultiIndex, use the MultiIndex.set_levels() method. The parameter level is used to set the level name.At first, import the required libraries −import pandas as pdMultiIndex is a multi-level, or hierarchical, index object for pandas objects. Create arrays −arrays = [[1, 2, 3, 4], ['John', 'Tim', 'Jacob', 'Chris']] The "names" parameter sets the names for each of the index levels. The from_arrays() is used to create a MultiIndex −multiIndex = pd.MultiIndex.from_arrays(arrays, names=('ranks', 'student'))Set the level in MultiIndex. We have set a new single specific level using the level ... Read More
