little project

I wanted to start a little project(very little) in python, to see if I learned something. Unfortunately, I didn't succeed so much.... I wanted to convert letters into signs( | , $...), I converted the letters into signs, but my problem was that no matter what order I wrote the letters, the order didn't change..... so here is my code

def translate():
    strange_list = []
    strange_ch = {"a": "|", "b": "*", "c": "$"}
    while True:
        print(''.join(strange_list))
        strange_input = input("write your sentence: ")
        if strange_input == "QUIT":
            break
        else:
            for key, value in strange_ch.items():
                if key in strange_input:
                    strange_list.append(value)

    print(''.join(strange_list))

The order is always |*$ do I need to change the whole code, a bit, or write a bit on top of it? am I even allowed to ask it? (: also, I noticed that if I write the letters separately one after another it does show me the order I gave. but if I write all of them in one line it doesn't.

Thanks anyway.

Idan.
