This works fine in workspaces, but not in the code challenge?

Question

This challenge has several steps so take your time, read the instructions carefully, and feel free to experiment in Workspaces or on your own computer. For this first task, create a function named num_teachers that takes a single argument, which will be a dictionary of Treehouse teachers and their courses. The num_teachers function should return an integer for how many teachers are in the dict.

teachers.py

# 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(x):
    new = []
    for thing in x.keys():
        new.append(thing)
        return len(new)

Check your indenting.

Your return statement is inside the loop and because of that you're returning the total of teachers after each iteration of the loop. So let's say you have a dictionary with 10 teachers this will be your output:

1

2

3

4

5

6

7

8

9

10
