How to Change the Formatting for My Return Values in This Function

How do I change the formatting for my return values in this function?

If your function is return a table then you should treat it like a table. How do we normally look at tables in SQL? We SELECT ... FROM them. You're looking for something more like this:

select ...
from nrt_summary_by_param_id(5);

PHP return value formatting

in your function you concating two strings in first condition, in second condition returned an empty string and in else statement returned that self price without change. so as your return type is string there is no problem for merging your prices with another strings such as html tags. if this process don't make problem for another processes of your wordpress, you can use html tags by concating them in your returns:

function sr_change_variable_price($price, $product){
    $html_tag = '<span style={some styles}>%s</span>';
    if($product->is_type('variable') AND !is_product()){
        $min = $product->get_variation_regular_price('min') . ' ' . $product->get_variation_sale_price('min');
        $min = $min ' Ft';
        return(sprintf($html_tag, $min));
    }elseif($product->is_type('variable') AND is_product()){
        return('');
    }else{
        return(sprintf($html_tag, $price));
    }
}
add_filter('woocommerce_get_price_html', 'sr_change_variable_price', 10, 2);

string.Format Return value of pure method is not used

You need to render the value in a code block like this:

@if (Model != null && Model.Order != null)
{
    foreach (var item in Model.Order.Where(x => x.OrderInStep2 != null))
    {
      <text>@String.Format("{0:C}", item.OrderInStep2)</text>
    }
}

Return a multiple value dictionary within a function into a pretty format

Dictionaries (like all built-in containers) are represented with their contents shown as representations, essentially using the repr() function on each. For strings, those are meant to be as helpful as possible in that they are shown as string literals that can simply be copied and pasted to recreate their value. That means they also show unprintable characters or characters with special meaning as escape sequences. Your newline characters are just such characters.

In other words, you can't do what you want just by inserting \n characters in the string values.

Instead, you need to do your own formatting if you really want to show your dictionary that way. Just print out the keys and values yourself:

def represent_dict(d):
    print('{', end='')  # no newline
    first = True
    for key, value in d.items():
        # newline at the start, not end, with commas
        print('{}\n{!r}: {!r}'.format('' if first else ',', key, value), end='')
        first = False
    print('}')  # closing with a brace and a newline

Remove the \n addition in your reading code; it can be simplified to just produce the dictionary directly with a dictionary comprehension:

def read_dictionary():
    with open("text.tsv") as tsvfile:
        tsvreader = csv.reader(tsvfile, delimiter = "\t")
        return {row[0]: row[1:] for row in tsvreader}

represent_dict(read_dictionary())

You generally should keep presentation and data structure separate. Those newlines in the keys can easily cause issues elsewhere, and they are only there for the presentation output.

Demo of the output:

>>> dictionary = {"string1":["a","b","c"], "string2":["d","e","f"],
...               "string3":["g","h","i"], "string4":["j","k","l"]}
>>> represent_dict(dictionary)
{
'string1': ['a', 'b', 'c'],
'string2': ['d', 'e', 'f'],
'string3': ['g', 'h', 'i'],
'string4': ['j', 'k', 'l']}

Return value of a function in Erlang

In Erlang the last expression in your function is returned, in your case that would be the result of io:format which is ok.

To return Cmd you can simply make it the last expression in your function:

function_test() ->
    Cmd = os:cmd("ls"),
    io:format("The result of ls is:~p~n", [Cmd]),
    Cmd.

Date Function in Insert gives an error. How can I format my date to return the insert values?

This line is the problem:

(18316,'p2','NULL','01-juni-2019'),
-----------------------^^^^ what month is "juni"?

This works:

(18316,'p2','NULL','01-jun-2019'),

But really, you should be using unambiguous formats that don't contain language-specific words, like 20190601. Otherwise this can still fail, e.g.

SET LANGUAGE German;
INSERT ... VALUES (18316,'p2','NULL','01-jun-2019')

Msg 241 Level 16 State 1

Fehler beim Konvertieren einer Zeichenfolge in ein Datum und/oder eine Uhrzeit.
