Oy vey.

So the first time through, you are setting the second column of wert. Then l
(btw, never, ever use lower-case "l" as a single-letter variable name; it looks
like "1") gets incremented to 2, which would try to put data into the third
column of wert. However, wert only has two columns.

Are you aware that numpy array indices start with 0, not 1?

You will probably want to ask numpy questions on the numpy-discussion mailing list:
