1,311 PointsCode Challenge - Teacher Stats task 5
I'm stuck on task 5. I can get this dictionary to be converted to a list but having trouble replaceing the sublist with the length of the sublist.
def stats(teachers):
teacher_list = []
for i in teachers.items():
teacher_list += i
for j in teacher_list:
teacher_list.replace(len(teacher_list[j]))
return(teacher_list)
I tried another approach which drew from task 4 using "key, value" variables but without success
def stats(teachers):
teacher_list = []
for key, value in teachers.items():
teacher_list.append([key, len(teachers[value])])
return(teacher_list)

", you're attempting to use the value as a key. What you probably meant to do was "teachers[key]
", but that's not even needed since you already have "value
" and can use it directly.
teacher_list.append([key, len(value)])

1,311 PointsThanks Steven. That fixed it. I saw the key, value approach in a few youtube videos and the like and though it works I don't fully understand the sequence of operations. Are either of the following the correct intuition?
Thanks again

231,275 PointsThe first description is more accurate. The keys and and sizes are being appended together inside a mini-list.
