Would like to get any explanation about my mistake..
# 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):
return len(dict.keys())
def num_courses(dict):
s=0
for k,v in dict.items():
s=s+len(v)
return s
def courses(dict):
courses = []
for value in dict.values():
courses += value
return courses
def most_courses(dict):
teacher = ""
top_amount = 0
for key, value in dict.items():
if len(value)> top_amount:
top_amount = len(value)
teacher = key
return teacher
