Homework 5.3: Note: it is okay if your procedure produces an error if the input hexamester is not included in courses.

0

Why?? I showed my code throws an error if the input hexamester is not included in courses and my code was considered wrong!!! It's unfair!!! I removed the example "print is_offered(courses, 'cs003', 'dec2012')" at the end of my page and my exercise is correct!! I don't want complain of automatic corrections, but I'm a bit vexed!!

My solution:

def is_offered(courses, course, hexamester):
    clist = courses_offered(courses, hexamester)
    if course in clist:
        return True
    return False

My code works exactly like yours and it was graded correctly. Judging from the other posts, I guess there was a bug in the grading script.

My submission was:
def is_offered(courses, course, hexamester):
return course in courses_offered(courses, hexamester)

I know what is the problem, at the end of my page I'm used to writing some examples, as follow:

print courses_offered(courses, 'apr2012')
print is_offered(courses, 'cs101', 'apr2012')
print is_offered(courses, 'cs003', 'apr2012')
print is_offered(courses, 'cs003', 'dec2012')

The last one only to demonstrate that the code throws an error when it is runned, (how the Node required). Removing the last example and pushing "submit" again, my answer is considered correct!!
For this reason I'm saying that the automatic correction is unfair!!
