Python Python Collections (Retired) Dictionaries Teacher Stats

teachers.py

I think I'm on the right track, but now I'm stuck. Any assistance appreciated.

teachers.py
# 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(my_dict):
    max_count=0
    busy_teacher=''
    for x,y in my_dict.items():
        if len(y)>max_count:
            max_count=len(y)
            busy_teacher=x
    return busy_teacher

def num_teachers(my_dict):
  return len(my_dict)

def stats(my_dict):
  count=0
  myList=[]
  for key in my_dict:
    count +=1
    myList.append()
    return my_dict[key]

For your stats function here's a few things you can do:

  • Remove the count variable. Instead you can pull out both the key and the value in the for loop and check the length of the value to avoid an extra loop.

  • In the loop, create a new list for each dictionary pair and assign it to myList with append.

  • Move your return statement out of the for block back into the function block.
