title: How to remove a selected rows from dataframe under a condition
body: <p>I have a large data with 12 columns. Where MatchId is duplicated.</p>
  
  <pre><code>df1.columns
  Out[569]: 
  Index(['MatchId', 'Event_Id', 'EventCode', 'Team1', 'Team2', 'Team1_Goals',
         'Team2_Goals', 'xG_Team1', 'xG_Team2', 'CurrentPlaytime',
         'Home_Goal_Time', 'Away_Goal_Time'],

  <p>For the condition, <code>df1.loc[df1.Home_Goal_Time &gt;= 200, 'MatchId']</code>, I want all the MatchId associated with this condition to be removed from <code>df1</code>.</p>
