Q2 Quiz2

Posted by Chaoran Huang Tuesday 26 March 2019, 12:42:31 PM.

After discussion and talking with some students, we realized that there exist an ambiguity in q2 in quiz2

"The question should have been specific to be " Given a DataFrame, apply the z-score normalisation if possible, else keep the column unchanged ". The question is misleading and no one would expect the hidden condition applied, and even shown on the lecture, we see that we have a lambda expression which we could not expect."

Thanks Michael Tran for pointing this out, and everyone will get 1 mark for this question.

Clarity on q1 and q6 about the assignment

Posted by Xiaocong Chen Tuesday 19 March 2019, 10:32:42 AM.

For those students who may not finish the assignment 2, we want to make some clarity about the q1 and q6 to make your life easier. For q1 the <collection> in your API can be any string you defined which means you can make you URL like /hello/<id> or /bye/<id> or something else. Just make a comment on your swagger page. For q6, as the note said you need to consider about the case if the country code is null, after discussion, you can ignore this restrictions which means if you put the “country” which country code is null will not lose mark, if you only put the “country” which have country code will not lose mark as well. For those students who already finished, this clarification should not affect your code.

Part of indicator you can use to test

Posted by Xiaocong Chen Monday 18 March 2019, 06:43:10 PM, last modified Monday 18 March 2019, 06:46:28 PM.

Census date today - SUN 17 MAR 2019

Posted by Lina Yao Sunday 17 March 2019, 12:09:15 PM.

A quick reminder that today, 17 March is the last day to
withdraw from courses without being charged fees for them(by 11:59).

To maintain full-time status, it is safest to remain enrolled
in at least 2 courses in T1 (and you would then need to take
3 courses in each of T2 and T3).

The Database Name for assignment 2

Posted by Xiaocong Chen Thursday 14 March 2019, 11:13:43 PM.

As we made a mistake of the code template, so the database name is: data.db
