Are there any ways i can take 1 letter from a word, and then mix that letter with another letters choosen from other words

Title is complicated yeah, but i will show an example what i want to achieve..

So i give a list of words

keywords = ['paper', 'car', 'plane', 'keys']

Then i take 1 or more letters from each of those words in the keywords list and mix them together in a 1 random word like this

word: pany
word: rpars
word: sprya

ofc i want to run this on a loop for like 100 times, but i need to get the general part done first

thanks!
