How to randomly choose a string from a list, and insert it into a new one?
Question: I've recently made this program to simulate the concept of random generation
with my example being trees, however I don't understand why I can't find an
element within the list with a randomly generated number. I tried
`Leaves.index()` but It doesn't seem to be working. Are there any ways to
randomly take a string from one of my lists and add it into another list?

    
    
    import random
    
    Leaves=["Pointy","Rounded","Maple","Pine","Sticks"]
    Trunk=["Oak","Birch","Maple","Ash","Beech","Spruce"]
    Size=["Extra Large","Large","Medium","Small","Tiny"]
    Tree=[]
    while len(Tree)<len(Leaves)*len(Trunk)*len(Size):
        NewCombination=Leaves.index(random.randrange(len(Leaves)))+Trunk.index(random.randrange(len(Trunk)))+Size.index(random.randrange(len(Size)))
    if Tree != NewCombination:
        Tree=Tree+NewCombination
    print(Tree)
    

Error:

`Traceback (most recent call last): File

Answer: From what I can tell, it seems like you want to create a list of a bunch of
random features. The way I would personally go about this is by using the
random method `Choice`

Choice allows us to pick a string from a list, then we use a function called
`.append` that lets us include it in another list

    
    
    from random import choice
    
    Leaves=["(Pointy ","(Rounded ","(Maple ","(Pine ","(Sticks "]
    Trunk=["Oak ","Birch ","Maple ","Ash ","Beech ","Spruce "]
    Size=["Extra Large)","Large)","Medium)","Small)","Tiny)"]
    Tree=[]
    NewCombination = []
    
    while len(Tree)<len(Leaves)*len(Trunk)*len(Size):
        NewCombination.append((choice(Leaves)) + (choice(Trunk) + (choice(Size))))
    
        if Tree != NewCombination:
            Tree=Tree+NewCombination
    print(Tree)
    

I have also made it much easier to see the printed list by including brackets
and spaces in your original three lists
