For tangling: you could put from = __future__ imports into the :shebang and use padline ":padline no", = i.e.:

#+source: = the_test

#+begin_src python :var x=3D3 :tangle test.py = :results output :shebang from __future__ imports :padline no

print x

#+end_src

which = results in

from __future__ = imports

print x

Keep in mind, = that I have NEVER used python (although I = should=85).

While I'd not call = that a clean solution to the problem it will keep me going for = now.

Thank you very much for pointing = that possibility out, I haven't thought about trying to move the import = statement.

As for python: its a nice = language worth trying in my opinion ;) =

With this i could do the = table calculation manually by inserting 100-1000 call statements (in the = real use case I need for my masters-thesis) but it would be really nice = if i could use a table cell as argument for = code-blocks.

A second problem I have at the moment lies with the execution of = source-blocks in tables. What I'd like to do:

| argument | result |
| 1 | #ERROR |
| | |
#+TBLFM: $2=3Dcall_the_test(x=3D$<)

I guess I'm just doing something wrong here. Executing the #+Tblfm = results in the error: "reference $< not found in buffer". How do I do = the reference correctly in this case?

You can test both cases in the attached = org-file.

best regards,

Dirk
