dict = {'a': 'a1', 'b': 'b1'}
list = [a1]

...

print('key from a1 is: (key x)')

`

I want to decrypt the message, but dont know how. (I am a beginner!)

So that when se user types in o78t6df the code prints out A. But i need this for whole sentences.

Can someone help me?

Welcome to StackOverflow. "I tried some own code." Then show your work so far so readers know what you've tried already. — Abirbhav G., Dec 13 '22 at 09:07
Shouldn't it be `list = ['a1']` (and by the way, DON'T name your list `list` : you're overwriting a Python keyword, which can be bad! — Swifty, Dec 13 '22 at 09:09
@Swifty correct suggestion but not a keyword, just a built-in type. If it was a keyword then it would not have been possible to overwrite — DeepSpace, Dec 13 '22 at 09:10
@Swifty yes i know, in my code the list is named characters_list, i just wrote it as an example — Gimojy, Dec 13 '22 at 09:19
I imagine your `dic` is used for coding a message; perhaps you want to create a reversed dic for decoding ? In this case, this might help: https://stackoverflow.com/questions/483666/reverse-invert-a-dictionary-mapping — Swifty, Dec 13 '22 at 14:45

your description is confusing. but seems you are looking for something like this.

my_dict = {'a': 'a1', 'b': 'b1'}
my_list = ['a1']
for item in my_dict:
    if my_list[0] == my_dict[item]:
        print('key from a1 is: {}'.format(item))

if it's your goal so end. if not edit your question with more explanation.

edit: if your list contains more, use another for for that!

... which beats the entire purpose of using a dict. If OP needs this they might as well build the dict the other way around – DeepSpace Dec 13 '22 at 09:23
