I tried so hard to make this challenge work on my own, but i am still a 'BIG GREENHORN' in programming(i know the commands, but i don't know when to implement them), can someone please give me direction to complete this challenge? What should i write inside the function "num_courses"? P.S: the function 'num_courses' needs to return the total courses of all the teachers.
# 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(value):
return len(value)
def num_courses(value):
total_number = 0
for i in value.values():
total_number += 1
return total_number

You need to unpack the courses from the dictionaries:
In this case, i will return the teacher name and value[i] will return the courses for that teacher.
total_number = 0
for i in value:
total_number += len(value[i])
