Create a function named most_classes that takes a dictionary of teachers. Each key is a teacher's name and their value is a list of classes they've taught. most_classes should return the teacher with the most classes.
I am stuck for more than a day now! Please help! Here is my code:
td = {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'], 'Kenneth Love': ['Python Basics', 'Python Collections']}
def most_classes(td):
tempv = []
k = list(td.keys()) # <-- turning all keys in the dictionary into a new list - k = []
v = list(td.values())# <-- turning all values in the dictionary into a new list - v = [[]], output is list within a list
i = len(v) # <-- defining the length of a sub_list
for sub_list in v: # <-- looping though sub_lists
tempv.append(len(sub_list[0][i])) # <-- replacing names of subjects (values) with an int (just a number of subjects),
# <-- and turning it into a new list tempv = [] where numbers reflect number of subjects taught by each teachers
return k[tempv.index(max(tempv))] # <-- returning the corresponding index value in the teachers names (keys in dictionary)

Front End Web Development Techdegree Student 4,005 PointsThis should work here :
def num_teachers(my_dict):
return(len(my_dict))
def most_classes(my_dict):
max_count = 0
for key in my_dict:
if len(my_dict[key]) > max_count:
max_count = len(my_dict[key])
answer = key
return answer

Courses Plus Student 5,567 PointsGreat answer, this is an easier snippet of code to understand :
def most_classes(teacher_dict):
max_count = 0
best_teacher = ''
for teacher in teacher_dict:
if len(teacher_dict[teacher]) > max_count:
best_teacher = teacher
return best_teacher

I have no idea the reason when I test on compute work well and give me correct answer but not work well on the website.
