Extracting part off an element in a list python

Im trying to extract only the string part of an element in my list put i can only figure out how to append the int.

this is my list:

{"Java": 10, "Ruby": 80, "Python": 65}

i want the output to be the languages with a grade higher than 60.
in that case

"Ruby", "Python"

this is my code but with the append function i can only extract the grade.

def my_languages(results):
    output = [] 

    for i in results:
        if results[i] >= 60:
            output.append(results[i])
    return output

Thank you all in advance

>Solution :

When we traverse the dictionary, the key of the dictionary is index, that is, I, so you need append to be “i”.

def my_languages(results):
    output = [] 
    for i in results:
        if results[i] >= 60:
            output.append(i)
    return output
