<div class="w3-show-inline-block">
    <div class="w3-bar">
        <h4 class="w3-wide">Сортировать по:
        <button name="sort_complexity_ascending" class="w3-button w3-black">сложности от 1 до 5</button>
        <button name="sort_complexity_descending" class="w3-button w3-black">сложности от 5 до 1</button>
        <button name="sort_alphabet_ascending" class="w3-button w3-black">алфавиту от А до Я</button>
        <button name="sort_alphabet_descending" class="w3-button w3-black">алфавиту от Я до А</button></h4>
    </div>
</div>

if request.method == 'GET':
        if request.GET.get("sort_alphabet_ascending"):
            history = sort_alphabet_ascending(history)
        elif request.GET.get("sort_alphabet_descending"):
            history = sort_alphabet_descending(history)
        elif request.GET.get("sort_complexity_descending"):

        elif request.GET.get("sort_complexity_ascending"):
            history = sort_complexity_ascending(history)
