Problems with dictionaries in python

Question

translator = input("Enter a japanese word: ")

japanese_to_english = {
    "Konichiwa": "Hello",
    "baka": "fool",
    "gomen": "sorry",
    "sugoi": "awesome",
}

from the code given above, when the user types a word which is inside the dictionary.. I want it to replace the words.. it there any short way of doing this .. Please let me know... Thank you!

What do yo mean by replace the word? You want to replace the `key` or `value`. Where is the code that you had tried? — Prudhvi, Apr 17 '20 at 06:02

To access a value from a key, the notation is mydict[mykey] or mydict.get(mykey)

translator = input("Enter a japanese word: ")

japanese_to_english = {...}

english_word = japanese_to_english[translator]       # raise error if word not in dict
english_word = japanese_to_english.get("translator") # return None if word not in dict

Try:

translated = ' '.join(japanese_to_english[i] if i in japanese_to_english else i for i in translator.split())

Here, we split the input by space, checks them if they are inside the dict, if so replaces it. If not found the word is not replaced.
So if you input:

Konichiwa i am gomen

you get:

'Hello i am sorry'

An answer without details values nothing, you can't just tell the OP "Do this" without explaining how it solves its problem and what it does – azro Apr 17 '20 at 06:04
I did not downvote, maybe the problem was that the OP did not talked about multiples words, don't know – azro Apr 17 '20 at 06:09
