Does she do it all the time or just when you take her out to feed? First your temps are too cool warm side should be 90-92 and cool side should be 80-85. Also there is no need to take her out of her enclosure to feed that is a myth and does more harm then good. Ball Pythons aren't aggresive animals they don't just take an aggressive disposition for no reason. Your hand could smell like prey if your handling the food item before trying to handle the snake. Just something to think about. Raise your temps and feed in enclosure, don't handle day of or day after feeding and she should settle down.
