1. Set cell values in the entire DF using replace() We’ll use the DataFrame replace method to modify DF sales according to their value. In the example we’ll replace the empty cell in the last row with the valu
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 ...
