Why is there a SyntaxError?

stage.py 
def stats(dict_tea):
    li = []
    for key in dict_tea:
        add = [key, len[dict_tea[key]]
        li.append(add)
    return li

And here's the code that I tested the function.

test.py 
test_dict = {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
 'Kenneth Love': ['Python Basics', 'Python Collections']}
print (stats(test_dict))

I can't figure out why it kept giving me an SyntaxError at the "li.append()"? Any idea about that?

Your error is not at

li.append()

but at

[key, len[dict_tea[key]]

Can you see the syntax error.
