im really lost in this challenge and would appreciate if anyone can explain it
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(my_dict): teachers_list = {'andrew': ['jquery', 'node'], 'kennneth': ['python']} for teacher in my_dict: teachers_list[teacher] = len(my_dict[teacher]) return max(teachers_list)

def num_teachers(dict):
len_dict=len(dict)
return len_dict
you don't need a teacher list ,it I already there.
sorry the code isn't displaying right, if you type it is will work

Courses Plus Student 1,356 PointsHi there! First , the dictionary that you must use in your code is not exactly the one that is shown in the example.It can be one with more keys. So you don't need : teachers_list = {'andrew': ['jquery', 'node'], 'kennneth': ['python']}
in order to loop through the teachers inside the dictionary , you have to use .keys() method like this: for teachers in my_dict.keys() This allows you to loop only through the teachers. Create a empty variable : number_of_teachers[] , like this, and append every teacher with append() method, so you'll have: for teachers in my_dict.keys(): number_of_teachers.append(teachers) Then in a new variable that you create you will place the length of number_of_teachers like this: new_variable=len(number_of_teachers) And at the end you will return new_variable. Hope this helps. Let me know if you hace questions.
