$roll conversion error

[celeste-42bit]

Parsing out all the numbers from the argument using re.findall(r'\d+', die) returns a list, which can't be converted into an integer with int().
I assume joining the characters together would return a String of numbers, which can be cast into an integer to then do the comparison later in the code.

async def roll(ctx, die: str, amount: int):
    number_characters = re.findall(r'\d+', die)

    if not number_characters or number_characters < 2:  # Comparison only works between congruent types!!! (Error: list < int)
        await ctx.send(f'"{die}" is not a valid dice.')
        return

I fixed the issue by joining the list into a string of numbers and then casting that into an integer.
This led to another issue.

If the list is empty, int() will error out.
