In C#, I have a width I want to use for some strings, but I won't know that width until runtime. I'm doing something like this:
string.Format("{0, " + digits + "}", value) // prints 123 as " 123"
Is there a string formatting directive that lets me specify this without smashing my own format string together like this?
I looked around on MSDN for a little while and I feel like I'm missing a whole chapter on format strings or something.

Python's str. format() method of the string class allows you to do variable substitutions and value formatting. This lets you concatenate elements together within a string through positional formatting.
In java, String format() method returns a formatted string using the given locale, specified format string, and arguments. We can concatenate the strings using this method and at the same time, we can format the output concatenated string. Parameter: The locale value to be applied on the format() method.
Use a formatted string literal to print a string at a fixed width, e.g. print(f'{my_str: <6}') . You can use an expression inside of a formatted string literal where you can specify the width of the string and the alignment. Copied!
Take a look at PadLeft:
s = "123".PadLeft(5); // Defaults to spaces
s = "123".PadLeft(5, '.'); // Pads with dots
