# %% English
# 1. Use `DATA: dict` - with pilot's phonetic alphabet
# 2. Ask user to input letter
# 3. Define `result: str` with phonetic pronunciation of a letter
# 4. If the character does not exist in the alphabet, assign: 'Missing'
# 5. Non-functional requirements:
#    - User will always put only one capitalized letter
#    - User will not input any invalid characters or numbers
#    - Do not use `if`, `try`, and `except`
#    - `Mock` will simulate inputting `W` letter by a user
#    - Use `input()` function as normal
# 6. Run doctests - all must succeed

# %% Polish
# 1. Użyj `DATA: dict` - alfabet fonetyczny pilotów
# 2. Poproś użytkownika o wprowadzenie litery
# 3. Zdefiniuj `result: str` z fonetyczną wymową litery
# 4. Jeżeli znak nie istnieje w alfabecie, przypisz: 'Missing'
# 5. Wymagania niefunkcjonalne:
#    - Użytkownik zawsze wpisze tylko jedną wielką literę lub cyfrę
#    - Nie używaj `if`, `try`, i `except`
#    - `Mock` zasymuluje wpisanie litery `W` przez użytkownika
#    - Skorzystaj z funkcji `input()` tak jak normalnie
# 6. Uruchom doctesty - wszystkie muszą się powieść

# %% Hints
# - `input(prompt)`

# 1. Use `PL: dict` with Polish diacritic characters

# 1. Użyj `PL: dict` z polskimi znakami diakrytycznymi
