Courses Plus Student 2,961 PointsFlatten a list
The third function named courses is the focus. I have tried out the code in workspaces and so far I can get a list of the courses without repeating any course already added. But I need to flatten the list. I have checked online but the explanations are not simple. I need to flatten the list to make a single list. Please help explain how this is done. Thank you.
# 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):
new = dict
number = len(new.keys())
return (number)
def num_courses(dict):
count = 0
for teacher, courses in dict.items():
if type(courses) is list:
count += len(courses)
else:
count += 1
return (count)
def courses(dict):
num = []
for teacher, courses in dict.items():
if courses in num:
num.remove(courses)
else:
num.append(courses)
return (num)

def courses(dict):
num = []
for teacher, courses in dict.items():
if type(courses) is list:
for course in courses:
num.append(course)
else:
num.append(courses)
