otsu threshold in python

Hy guys.
I'd like to ask you for a favour.
I tried several times to implement the otsu threshold filter in
python. but I failed every time. I found the soucre code i n Java from
the ImageJ project but I never worked in Java and there have been used
some built in Java functions which I don't know how they behave. I
also found the otsu threshold in the ia636 python module and would
like only this filter and don't want to import this library.
Is there anyone who wold like to help me. I need a function that takes
a list of 256 elements as an argument and returns the threshold values
for the threshold according to Otsu.

In addvance, I don't expect someone to do my homework. I really tried
it, I have been googling and didn't find a standalone function. I
wasn't able write a standalone function because I don't understand the
Otsu method. I just know that it works well and that I need it.

If there is no one that wants to help me with this problem, can
someone at least explain me in a detailed way how to implement it.

Thanks
