As stated above, use the very flat of your hand. It's a super super super super difficult thing to do... and you feel like a douche bag for not being able to. Wait until the snake is under a hide or similar, then simply lift the hide up and slowly (not too slowly, you still need to be reasonably quick) put your hand down into the enclosure as if you're going to high five the snake's face. If it bites, you will not see it coming as the face will be behind your hand in the line of sight. You'll feel it... but it will be like somebody tapping you on the shoulder (if that). It's nearly impossible for a python to penetrate the skin in this manner.
Most of all... you really really really really need to be calm. If you're stressed out you'll make jerky movements and the snake will get more stressed. I remember I used to shake like a leaf when I was attempting to deal with my python... but you'll only get better with experience.
If you're seriously still getting absolutely petrified of the little one... use a tea-towel on your hand (just single layer, the teeth won't be able to get through... they're tiny) and cover the snakes head. Bring in your other hand and pick the snake up with the other end of the tea-towel. It will most definitely stress out and start flipping about and possibly hissing, but you need to be calm. Wrap the snake up into a ball (it may want to do this anyway as their first instinct is to hide) and cup it with your hands in a cave-like manner (still with the tea-towel between you and the snake). After a while, you can wrap it up in a ball and then start introducing a bare hand as the top of the cave. This way, they'll familiarise themself with your smell.
No amount of people telling you "Oh, it won't hurt"... "Just man up"... "Try this technique" will ever really help you. You need somebody there to show you... then you can be more confident that these techniques will work. See if you can find a local member in your area that can help out (I was down Liverpool way last night... but that doesn't really help now!).
Good luck!
