Hi everyone! I am trying to create an English Thesaurus which the user is going to write an word as input and get the corresponding meaning, also if the user inputs a non-existing word than program has to output the variable m.
Unfortunately my code outputs m either way.
I'll be appriciated any help of you, thanks.

import json
data = json.load(open("data.json"))

def dictioanry(inp):
    m = "The word doesn't exist. Please double check it."
    for k in data.keys():
            if inp != k:
                return m
            else:
                answer = data[k]
                return answer

    
print(dictioanry(inp = input("Enter Word: "))) 

Output:
Enter Word: rain
The word doesn't exist. Please double check it.

And this is what corresponds to rain in data:

Output:
>>> data["rain"]
['Precipitation in the form of liquid water drops with diameters greater than 0.5 millimetres.', 'To fall from the clouds in drops of water.']
