Getting multiple outputs from my dictionary when I need only one

December 10, 2021

Im having a little problem with only printing the corresponding abbreviation that is stored in a dictionary

user = input("Enter a Abbreviation: ")

dictionary = {"ADSL": "Application Programming Interface",
              "IDE": "Integrated Development Enviroment",
              "SDK": "Software Development Kit",
              "UI": "User Interface",
              "UX": "User eXperience",
              "OPP": "Object Oriented Programming"
              }

for x in dictionary:
    if user in x:
        print(user + ":" + " " + dictionary[x])

    elif x != dictionary:
        print("Abbreviation not found")

This is my output

Enter a Abbreviation: UI
Abbreviation not found
Abbreviation not found
Abbreviation not found
UI: User Interface
Abbreviation not found
Abbreviation not found

I only need the entered abbreviation key value not all the Abbreviation not found outputs, I hope this makes sense

>Solution :

The good point of a dictionary is that is "indexed" so you don’t need to find the key. You are following a array approach, and that is a wrong approach.

user = input("Enter a Abbreviation: ")

dictionary = {"ADSL": "Application Programming Interface",
              "IDE": "Integrated Development Enviroment",
              "SDK": "Software Development Kit",
              "UI": "User Interface",
              "UX": "User eXperience",
              "OPP": "Object Oriented Programming"
              }

if user in dictionary:
   print(user + ":" + " " + dictionary[user])
else:
   print("Abbreviation not found")

You can find more information about dictionaries here, here and on google. It is very important to know when to use arrays, dictionaries, lists, queues…
