assign a variable using dataframe index and column names python code example

Example 1: pandas set a column as index

df = pd.DataFrame({'month': [1, 4, 7, 10],
                   'year': [2012, 2014, 2013, 2014],
                   'sale': [55, 40, 84, 31]})

df.set_index('month')

Example 2: python - give a name to index column

df.index.name                      # Show me the current name
df.index.name = 'my_column_name'   # Change the index name to my_column_name
