In my dictionary i have four values in my dictionary in my dictionary. I should it get back the value 4 but i get back 7...could someone explain where i am going wrong
# 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(teachers):
count = 0
for teacher in teachers.keys():
count +=1
return count
def num_courses(teachers):
for value in teachers.values():
total = len(value)
return total

The second function is just assigning the total value, so after the loop is over it will only contain the length of the last value.

Python Web Development Techdegree Student 5,158 PointsHi Steven
I was using my own dictionary which i wrote in pycharm.. The last value was English which was 7 characters hence that is where i got seven from. You indirectly gave me the answer as i need to re evaluate my code
cheers
