23,309 PointsWhat is in this dictionary
Hello,
I may be going crazy, but help me out here.
So, at first I thought the dictionary looked like this.
dict = {"Adam" : 7, John : 8, etc}
So I iterated through the dict and put the values into a list. Did a max on the list and found the highest number. Then I did a loop through the keys to return the value only if it was the max value. So needless to say this did not work. Didn't get the right teacher.
I then thought, ohh so it must be value then teachers. So like this
dict = {7 : "Adam", 8 : "John}
Well, again, I found the highest key and then got the value. This then returned a whole bunch of classes when it expected a name.
So now I am confused. It appears to me that it's asking me to count the number of classes each teacher has and print the teacher with the most classes.?
Now unfortunately the preview doesn't work. If I try to print the entire list just to see what I am working with. It just shows a black screen. At least on chrome. So I can't see the list I am trying to get. This makes it increasingly difficult to figure out.
Anyone have any suggestions.
# The dictionary will be something like:
# {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
# 'Kenneth Love': ['Python Basics', 'Python Collections']}
#
# Often, it's a good idea to hold onto a max_count variable.
# Update it when you find a teacher with more classes than
# the current count. Better hold onto the teacher name somewhere
# too!
#
# Your code goes below here.
def most_classes(dictOfTeachers):
T = []
for thing in dictOfTeachers:
T.append(thing)
A = max(T)
I = dictOfTeachers.get(A)
return I;

def most_classes(teachers):
# Keep track of the leading teacher
# Keep track of the leading teacher's course count
for key, value in teachers.items():
# If the length of the courses is longer
# Update the leading teacher and course count
return top_teacher

Yeah I totally didn't even read that lol. I am going crazy. I knew it! I just tossed it all into a list and used some index() and subtraction etc. Although a good hint would be try extends instead of append in some instances. Just saying for whoever might read this.
