Hey there! Let’s work through this sorting problem you’re dealing with. You want your results sorted first by count in descending order, and when two items have the same count, you want them sorted by name—super straightforward once you know the trick.

Let’s Use an Example to Make It Clear #

Suppose your current output looks like this (using a list of dictionaries as an example):

[
    {"name": "Banana", "count": 2},
    {"name": "Apple", "count": 3},
    {"name": "Cherry", "count": 2},
    {"name": "Blueberry", "count": 2}
]

And your desired output is:

[
    {"name": "Apple", "count": 3},
    {"name": "Banana", "count": 2},
    {"name": "Blueberry", "count": 2},
    {"name": "Cherry", "count": 2}
]

Solution in Python #

To pull off this multi-condition sort, we’ll use Python’s built-in sorted() function with a custom key. The key will be a tuple that first sorts by negative count (to get descending order) and then by name (to handle ties):

# Your original data
items = [
    {"name": "Banana", "count": 2},
    {"name": "Apple", "count": 3},
    {"name": "Cherry", "count": 2},
    {"name": "Blueberry", "count": 2}
]

# Apply the sorted logic
sorted_items = sorted(items, key=lambda x: (-x["count"], x["name"]))

# Print the result
for item in sorted_items:
    print(item)

If You’re Using JavaScript #

The same logic applies here—we’ll use Array.sort() with a custom comparator function:

const items = [
    {name: "Banana", count: 2},
    {name: "Apple", count: 3},
    {name: "Cherry", count: 2},
    {name: "Blueberry", count: 2}
];

items.sort((a, b) => {
    // First sort by count descending
    if (b.count !== a.count) {
        return b.count - a.count;
    }
    // If counts are equal, sort by name ascending
    return a.name.localeCompare(b.name);
});

console.log(items);

Core Idea for Any Language #

No matter which language you’re working in, the core approach is the same:

• First priority: Sort by count in descending order.
• Second priority: When counts match, sort by name (ascending, or whatever order you need for names).

This two-tiered sorting will give you exactly the output you’re looking for!
