I get "It looks like Task 1 is no longer passing." error for my code although it totally works in visual basic code. Can you please tell me what is wrong with the code?

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_courses(teach):
    list = []
    for value in teach.values():
        for item in value:
            list.append(item)
    count = 0
    for i in list:
        count+=1
    return count

Did you delete the first task? New content should go underneath previous tasks.

I had deleted the first task. I copied the solution for the first task and I completed the task. The code worked perfectly. Thank you very much. It was a small but annoying mistake.
