Bummer! Didn't get the right number of teachers!

No one of my codes passing!

Only show me: didn't get the right number

I am exhausted, in console seems to work.

Can anyone help me with this ?

Thanks

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(dict):
    dict = {
        'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'],
        'Kenneth Love': ['Python Basics', 'Python Collections']
    }
    teachers = 0
    for key in dict.keys():
        teachers += 1 
    return teachers

You are so close. Do not redefine the argument provided by the challenge checker. By reassigning dict, you overwrite the value used to test your code. Also, it's best not to use keywords as variable names. By using "dict" you overwrite the dict class.
