You can filter rows based on specific index labels using.loc[]or.filter()withitemsparameter. Use boolean indexing or.isin()method to filter rows based on a condition or a list of index labels. Use thelikeparameter in.filter()to include rows where the index labels contain a specific substrin...
Filter by Column Value:To select rows based on a specific column value, use the index chain method. For example, to filter rows where sales are over 300: Pythongreater_than = df[df['Sales'] > 300] This will return rows with sales greater than 300.Filter by Multiple Conditions:...
