= Zahl in String umwandeln =

 * Abgabetermin und Präsentationen: [[Treffen/2012-09]]

Ziel ist es eine Funktion bzw. Programm zu schreiben, das eine Zahl in einen String umwandelt und dabei Trennzeichen zwischen jedem Block von drei Ziffern einfügt.

Beispiele:

 * 10 => "10"
 * 1000 => "1.000"
 * 1000000 => "1.000.000"
 * 1999995.99 => "1.999.995,99"

Optional soll man die Trennzeichen angeben können, sodass die Zahl auch in andere Formate umgewandelt werden kann.

Beispiele:
 * 1000 => "1.000" oder "1,000"
 * 1000000 => "1.000.000" oder "1,000,000"
 * 1999995.99 => "1.999.995,99" oder "1,999,995.99"


=== Code Golf (optional) ===

If you want to participate in the ''shortest code possible'' contest where you have to ignore PEP-8 for once, these rules apply:

 * ''Program'': This script must be runnable as standalone script (read from stdin or files, or just use the "fileinput" module)
 * ''Library'': This script must be importable / usable as "library" (you can name the exported function "f")

Of course, you can combine both into one script as well. The script must be self-contained.

You can add your current status here (don't show the code until the meeting):
