[985] Filter by Column Value & Multiple Conditions in Pandas dataframe

ref: Ways to filter Pandas DataFrame by column values

1. 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: Python

     greater_than = df[df['Sales'] > 300]

   • This will return rows with sales greater than 300.

2. Filter by Multiple Conditions:

   • Use the & (and) or | (or) operators to filter based on multiple conditions. For instance: Python

     and_operator = df[(df['Sales'] > 300) & (df['Units'] > 20)]
     or_operator = df[(df['Sales'] > 300) | (df['Units'] > 20)]

   • and_operator filters rows where sales are greater than 300 and units are greater than 20.
   • or_operator filters rows where either sales or units exceed the specified thresholds.
