Welcome to coding exercise.

00:02.420 --> 00:06.980
We are here on the tuba that s part and our exercises file are still on the desktop

00:10.620 --> 00:14.490
and we are still in Part 1 and 2 we select the.

00:14.530 --> 00:16.770
The Tibetan notebook for exercise eight

00:22.540 --> 00:23.680
and an exercise eight.

00:23.680 --> 00:31.340
You would have to create and remove rows and columns and first of all we have to drop two columns.

00:31.480 --> 00:35.240
Then we have to drop some rows from Robert data frame.

00:35.350 --> 00:42.920
Then we have to add the two new columns based on existing columns then this is sheer repetition.

00:42.920 --> 00:49.220
We have to sort the data frame by a column from high to low and then finally you have to concatenate

00:49.220 --> 00:50.810
the three data sets.

00:50.810 --> 00:55.330
All three data frames so that's the exercise eight.

00:55.330 --> 00:58.690
I hope you have fun and I see you also on the solution by.
