Activate the virtual environment (see Install), then start the program:
The installed command does the same:
Spell a word
The program asks for a word and prints the NATO code word of each letter, in order. Upper and lower case give the same result.

Invalid input
A digit, a space or a punctuation mark is not a letter. The program says so and asks again.

Press Ctrl+C or Ctrl+D
Ending the input (Ctrl+D on Linux and macOS, Ctrl+Z then Enter on Windows) or pressing Ctrl+C closes the program quietly.
