734 Pointshelp with writing a function!
Create a new function named num_courses that will receive the same dictionary as its only argument.
The function should return the total number of courses for all of 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(dict):
value = 0
for i in range(len(dict)):
for key in dict:
value += 1
return value
def num_courses(dict):
count = 0
for value in dict.values():
count += 1
return count

14,867 PointsIt's only counting once and then returning 'count'. You'll need to fix the spacing on your return statement.
def num_courses(dict):
count = 0
for value in dict.values():
count += 1
return count
Also, the values in the dictionary are lists (2 of them) so even then it'll return 2 instead of counting each course individually. Personally, I used two loops. One went through the teachers and the other counted the courses for each teacher.
