Finding the position of an item in another list from a number in a different list

Question

Developing on my previous question I'm wondering whether there is a way to have an element in a list and find that position in another list and return what is in the position as a variable. for example:

list1 = [0,1,2,3,4]
list2 = ["0","hello","my","name","is","Daniel"]

if the user enters the number 14 the program will return "hello Daniel" in the sense that the computer reads 14 as 1 and 4 and finds the position in list as an example.

I've tired using [list2.index(x) for x in list1] hoping that it would work but I've been unable to change the code so it does work. is there a simple way to do it

Yes of course, you just need to turn `14` into individual digits and there are plenty of questions on that in SO. — AChampion, Mar 30 '17 at 17:04

@AChanpion I forgot to mention that I already converted 14 into a list itself by doing `list(14)` sorry for not mentioning it — D. Forrester, Mar 30 '17 at 17:07
Numbers are not iterable, `list(14)` wont work but `list('14')` will. — Satish Prakash Garg, Mar 30 '17 at 17:10
@SatishGarg my bad. then is there a way to convert 14 into two separate integer in a list? — D. Forrester, Mar 30 '17 at 17:12

I think that this will solve your problem: for x in list1: print list2[x]

Is it that what you were asking ?

You can do something like this :

input_num = 123
list1 = [0, 1, 2, 3, 4] # if list1 is not dervied from input number
list2 = ["0", "hello", "my", "name", "is", "Daniel"]
print(' '.join([list2[list1.index(int(ind))] for ind in str(input_num)]))

This will result in :

hello my name

Also, i would suggest you to look at the https://docs.python.org/2/tutorial/datastructures.html and trying things out to learn.
