Loop through all values in the "Duration" column. If the value is higher than 120, set it to 120: forxindf.index: ifdf.loc[x,"Duration"] >120: df.loc[x,"Duration"] =120 Try it Yourself » Removing Rows Another way of handling wrong data is to remove the rows that contains wr...
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...
