I'm new to Stack Overflow and Python. I'm trying to make a kind of translation program, I'm sure there is an easier way than what I'm doing, but hey that's part of learning. So basically the user inputs the letter, then the answer is translated, and printed. But I'd rather store it instead of print it, so that I can print the answer altogether at the end if that makes sense. 

```
`a = "b"
While True:
  i = input()
  if I_1 = a:
    L_1="a"
  if I_1 = b:
    L_1 = "b"`

```

etc..
So i want `L_1` to be stored each time, as `L_1`, `L_2` etc so at the end i can say 

```
`print(L_1 + L_2)`

```

and so on. 

I know I've probably used bad conventions but hopefully it's clear enough to understand.
Thanks.
