Full Stack JavaScript Techdegree Student 2,347 PointsMy code works (tried it many times with different combos) but the Recheck work function doesn't like it ... can sm help?
Hi,
Please see below my code, which works absolutely perfectly when I run it in the terminal with any set_of_topics combo. Weirdly the Recheck work function doesn't seem to like it... it might be a bug that's why I have asked my question here rather than on slack although I migh also I missed smth here so I am sorry if that's the case.. Thanks in advance.
def covers(set_of_topics):
relevant_courses = []
for course in COURSES :
if set_of_topics.issubset(COURSES[course]):
relevant_courses += [course]
return relevant_courses

But I think that the issubset() method returns a boolean if every element in x is in y. The intersection method returns a new set with the items that intersect. For the next challenge you will need a set of items and not a logical.
Let me know if this helped.

Full Stack JavaScript Techdegree Student 2,347 PointsI found a code that is accepted by the workspace in another thread which was a bit different that my code but produces the same output! Thanks a lot guys. Still not 100% sure why my code is not accepted though..

Full Stack JavaScript Techdegree Student 2,347 PointsSure - Here you go mate :
def covers_all(set_of_topics):
relevant_courses = []
for course in COURSES :
if set_of_topics.issubset(COURSES[course]):
relevant_courses += [course]
return relevant_courses

Full Stack JavaScript Techdegree Student 2,347 PointsAlso worth adding that I used my code for covers_all (2nd sub challenge) and it worked !

Full Stack JavaScript Techdegree Student 2,347 PointsOh thanks so much Grigorij ! It's very good to know wich methods are the most appropriate for a specific problem and indeed what you say makes a lot of sense to me. Merci !

Full Stack JavaScript Techdegree Student 2,347 PointsThank you so much for your help and for the explanations about the key differences between .issubset() and .intesection() methods. That's really helpful !
