python - How to get 80% random elements from a list?

Question

I have a list with integers. I want to choose 80% from them. For example, for [1,...,30] I want to keep 80% from the list with random so I get for example [1,...,32][3,7,19,21,25,29] (It means it deleted 3,7,19,21,25,29 values from the original list. How can I do it?
