Solve the following python programming problem given the following code:
def _preallocate(self) : 
    '
        The idea is to allocate space in front of an expanding db.  If it gets
        within 512k of a boundary, it allocates to the next boundary.
        Boundaries are 2m, 5m, 10m, 25m, 50m, then every 50m after.
        ' 
    if ((not DB_PREALLOCATION) or (self.db_file == ':memory:')) : 
        return 
MB = (1024 * 1024) 
    def prealloc_points() : 
        for pm in (1, 2, 5, 10, 25, 50) : 
            (yield (pm * MB)) 
while True : 
            pm += 50 
            (yield (pm * MB)) 
stat = os.stat (self.db_file) 
    file_size = stat.st_size 
    allocated_size = (stat.st_blocks * 512) 
    for point in prealloc_points () : 
        if (file_size <= (point - (MB / 2))) : 
            prealloc_size = point 
            break 
if (file_size < prealloc_size) : 
        with open (self.db_file, 'rb+') as fp : 
            fallocate (fp.fileno (), int (prealloc_size))
