Teacher Stats Exercise 1- Problem-how to return the key


Sorry for asking so much but how can I return the key fitting to the found value. You can see my code here:http://pastie.org/private/us8lcvr4rzoi6wqrcg4kfa The others methods don't work for me.

Thanks in Advance for help and Sorry for those many questions.

One way to do it would be to loop over the dictionary items directly (not just the values), and when you update the max_count, also save the key that goes with it. Then return the key when the loop is over.

For future postings, remember to include a link to the challenge page. And for info on including your code in your posting, see the Markdown Cheatsheet pop-up below the answer area. :arrow_heading_down:

This is my code. Maybe you can help me to bring it on the right way, so I can learn the most from it.

def most_classes (dict_of):
    for value in dict_of.values():
        if len(value)>max_count:
        return #key that fits to the value, this is my stucking point.

Thanks in Advance;)

def most_classes(dict):
    max_count = 0
    str = ""
    alist = dict.values()
    for key, value in dict.items():
        if len(value) > max_count:
            max_count = len(value)
            str = key
    return str

Thank you very much!
