Code is working fine but it doesnt pass here

# Each key will be a Teacher and the value will be a list of courses.

# Your code goes below here.

Treehouse TeacherHi there! Your code isn't returning a single teacher name, but rather returning a list of teacher names. Your code should return only one single teacher name... the name of the teacher who teaches the most courses. So instead appending that teacher name to a list you might consider making a variable to hold a single name of a teacher. Every time you find a teacher who teaches more courses, replace the name of the currently held teacher with the teacher that teaches more.
Hope this helps, but let me know if you're still stuck!

1,578 PointsThanks Jennifer, I am saving the name to variable instead of list and it passed.
why I chose the list because it is possible that more than one teacher may have same number of course.
Thanks for your response,
Thanks & Regards, Kaushal
