I am trying to create programs in python 3.4 all the challenge tasks but unable to print any of the outputs from the function. When I run nothing happens.
Here is the example:
dict_teachers = {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
'Kenneth Love': ['Python Basics', 'Python Collections']}
def most_classes(dict_teachers):
max_count = 0
for keys, values in dict_teachers.items():
if len(values) > max_count:
max_count = len(values)
busy_teacher = keys
return busy_teacher
print(busy_teacher)
def num_teachers(dict_teachers):
return len(dict_teachers.keys())
def stats(dict_teachers):
teachers_list = []
for keys in dict_teachers:
teachers_list.append([keys, len(dict_teachers[keys])])
return teachers_list
print(teachers_list)
def course(dict_teachers):
course = []
for keys in dict_teachers:
course.extend(dict_teachers[keys])
return course
print (course)

Treehouse Guest TeacherWhen you run a script (instead of just using it in the Python shell), and your script uses return everywhere (as it usually should), you won't see output because the output went back to Python itself.
Below your code, in your script, add lines like:
print(most_classes(dict_teachers))
print(courses(dict_teachers))
