Python IndentationError: too many levels of indentation

Question

I've a part of my python program which is generated, the generated codes contains a lot of nested if / else, my problem is that a lot can be too much and I got this Error when running my code:

IndentationError: too many levels of indentation

I've read that this was some limitation defined on the low level of the python interpreter, does anybody know how I can find a workaround for it? Some interpreter parameters would be fine, the only solution proposal I've found suggests to recompile Python in order to set a different value for the MAXINDENT constant, which is not exactly what I'm dreaming of.

EDIT : The code is a big bunch of nested if...else , it's dirty but it was the quickest I found to port a complex decision tree to Python. I know how dirty it is; I did not write it myself — I did not even plan to edit it (I would rather touch the generator).

I know I can modelize this decision tree in other fashions. What I would like is a way simpler than that, like tweaking the interpretor if possible.

EDIT 2 : Now I've done some refactoring, and my tree is stored as a dictionary: The loading of the file gives a new error :

s_push: parser stack overflow
MemoryError

Here again I found a resource suggesting some tweaks of the interpreter's headers.

Your generator is producing bad code. You should treat this exactly as you would if it were producing syntactically invalid code.

Use functions, dictionary dispatching and any other thing that might occur to you to reduce the depth.

OTOH, thanks for showing me that Python does really have a maximum depth. I didn't know that. :)
