Like other posters said, you should give more details with your question. 
What do you mean by equivalent?  The following is *functionally* equivalent:
    for n in range(start, 0, -1):

Of course, there is always:
    while n:
        ...
        n -= 1

But unfortunately, no, I don't think there is an equivalent in python that 
has the conciseness of the C statement.  The pre- and post-increment 
and -decrement in C/C++/Java are very powerful and I miss them in python.
