The Pandas set index method enables you to take one of the columns of a DataFrame and turn it into the index. Once we do this, we can reference rows by the index value (i.e., the “label”) associated with the particular row. The Pandas set_index method is the tool that we use to do this. The set_index() function is used to set the DataFrame index using existing columns. Set the DataFrame index (row labels) using one or more existing columns or arrays of the correct length. The index can replace the existing index or expand on it. Syntax: DataFrame.set_index(self, keys, drop=True, append=False, inplace=False, verify_integrity=False) By using set_index(), you can assign an existing column of pandas.DataFrame to index (row label).

It's not a bug. This is exactly how it's intended to work. DataFrame has to show show every single item in it's data. So if the index has one level, that level will be fully expanded. Set index when reading CSV file. When reading from a CSV file and generating pandas.DataFrame or pandas.Series, if the original file contains a column that should be used as an index, it can also be specified at reading.. When reading a file with read_csv(), specifying the column number in the argument index_col sets that column to the index.。 Python Examples. By default an index is created for DataFrame.
