1,230 PointsDictionary - counting the max element and returning a value of the key
Hi,
I tried the last function in python shell and it worked but i'm not sure what am i missing here (function name: most_courses)
The question: Create a function named most_courses that takes our good ol' teacher dictionary. most_courses should return the name of the teacher with the most courses. You might need to hold onto some sort of max count variable.
Thank you so much!
# The dictionary will look something like:
# {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'],
# 'Kenneth Love': ['Python Basics', 'Python Collections']}
#
# Each key will be a Teacher and the value will be a list of courses.
#
# Your code goes below here.
def num_teachers(arg):
return len(arg)
def num_courses(arg):
total = 0
for value in arg.values():
total += len(value)
return total
def courses(arg):
course_name = []
for course_list in arg.values():
for course in course_list:
if course not in course_name:
course_name.append(course)
else:
continue
return course_name
def most_courses (arg):
max_name = None
max_count = 0
for teacher in arg.keys():
for course_list in arg.values():
if len(course_list) > max_count:
max_count = len(course_list)
max_name = teacher
else:
continue
return max_name
