I think i missed something, but i can not see that. so help me please
# The dictionary will be something like:
# {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
# 'Kenneth Love': ['Python Basics', 'Python Collections']}
#
# Often, it's a good idea to hold onto a max_count variable.
# Update it when you find a teacher with more classes than
# the current count. Better hold onto the teacher name somewhere
# too!
#
# Your code goes below here.
def most_classes(a):
kkey = ""
maxc = 0
for i in a:
if len(a[i]) > maxc:
maxc = len(a[i])
for i in a:
if len(a[i]) == maxc:
return i
def num_teachers(a):
tnt = 0
tea = []
for i in a:
if i not in tea:
tea.append(i)
tnt += 1
return tnt
def stats(a):
dd = {}
for i in a:
dd[i] = len(a[i])
return dd

def stats(a):
dd = []
for i in a:
dd.append([i, len(a[i])])
return dd
