I agree. That old
"it will only grow to the size of the enclosure!" bit is nonsense, usually promoted by an unscrupulous dealer who is trying to sell you something that you are NOT capable of dealing with as an adult. Growth is controlled by temperature and how the animal is fed. The only thing you will accomplish by keeping the python in a too small enclosure is to make it aggressive and unpredictable. In a small enclosure they feel cornered with no place to run. So they BITE!
And just in case your friend gets the idea of controlling the snake's growth by not feeding it, this too will make it aggressive because it is constantly hungry.
So guess how it will view that nice warm hand coming into the cage.
