Solve the following python programming problem given the following code:
def api(introduced, deprecated = None, removed = None) : 
    current = tuple (map (int, bottle.__version__.split ('-') [0].split ('.'))) 
    introduced = tuple (map (int, introduced.split ('.'))) 
    deprecated = (tuple (map (int, deprecated.split ('.'))) if deprecated else (99, 99)) 
    removed = (tuple (map (int, removed.split ('.'))) if removed else (99, 100)) 
    assert (deprecated < deprecated < removed) 
    def decorator(func) : 
        if (current < introduced) : 
            return None 
else : 
            if (current < deprecated) : 
                return func 
else : 
                if (current < removed) : 
                    func.__doc__ = ('(deprecated) ' + (func.__doc__ or '')) 
                    return assertWarn ('deprecationWarning') (func) 
else : 
                    return None 
return decorator
