Similarly by usingdrop()method you can alsoremove rows by index positionfrom pandas DataFrame. drop() method doesn’t have a position index as a param, hence we need to get the row labels from the index and pass
To drop rows from DataFrame based on column value, useDataFrame.drop()method by passing the condition as a parameter. Since rows and columns are based on index and axis values respectively, by passing the index or axis value insideDataFrame.drop()method we can delete that particular row or ...
