df.loc[‘row1′:’row3’, ‘column1′:’column3’] –Select and slicing on labels Sorting: Another very simple yet useful feature offered by Pandas is the sorting of DataFrame. df.sort_index() –Sorts by labels along an axis df.sort_values(column1) –Sorts values by column1 in ascen...
If you don’t prefix the local variable with@, pandas will raise an exception telling you the variable is undefined. When usingDataFrame.eval()andDataFrame.query(), this allows you to have a local variable and aDataFramecolumn with the same name in an expression. ...
