    Yeah, you totally can combine the two format specifications into one:

    f"{int(number):>20,}"

    .

    Or, you could have asked this way:

    |Please fill in the implementation (replacing "pass" below) for
    |the following function definition!
    |
    |def format_number(number_str: str) -> str:
    | """
    | Format a string of digits as a right-aligned, comma-separated number.
    |
    | This function takes a string of digits and returns a formatted string where:
    | - The number is right-aligned in a field width of 20 characters
    | - Commas are inserted as thousand separators
    | - Leading spaces are added for alignment
    |
    | Args:
    | number_str (str): A string containing only digits (0-9)
    |
    | Returns:
    | str: A formatted string with the number right-aligned and comma-separated
    |
    | Examples:
    | >>> format_number("123456789")
    | ' 123,456,789'
    | >>> format_number("1000000")
    | ' 1,000,000'
    | >>> format_number("42")
    | ' 42'
    | >>> format_number("1234567890123456789")
    | '1,234,567,890,123,456,789'
    | """
    | pass

    Great. Thanks. Do you have a link to where that's documented?

    I did web search, found nothing.

    Stoked to hear you're into it!

    For docs, I usually snag the PDFs from "python.org," especially
    "reference.pdf" (the Python Language Reference) and "library.pdf"
    (the Python Library Reference), then I search them for keywords.

    The f-string stuff is laid out in "The Python Language Reference"
    since they're part of the language itself. A quick search for
    "f-str" gets you to "2.4.3 Formatted string literals," which says,
    "The result is then formatted using the format() protocol." So, you
    got to check out "The Python Library Reference" too! Searching for
    "format(" there zooms you right to "6.1.3 Format String Syntax"
    (via "Format Specification Mini-Language").

    But honestly, I usually just hit up a chatbot first. I'll drop
    in my code and say, "How can I make this shorter?".

    Thanks. I'll check those as time allows.

    Thanks, that's a good idea. I've usually gone for the web docs only.

    Great. Thanks. I'll try to remember that.

    In other words, a shortcut. :)
