I don't know if this the right forum to ask this.
Anyway, I think you might be missing explanation in general. For example, what a list is and what it tries to represent. Similarly, what classes are, instead of just examples. Also, I don't think beginners would look in a github repository firstly, before even knowing how to code.
I've seen a use of '''comment''', even though triple ' should be used (pep8) only for multiline strings and docstring, and not for comments (in example 5). In addition, I think you might update the README to relate for the requirements for each language.
