print("This is a Two-Way Morse Code Translator. This can translate any of the standard 26 letters and the numbers 0 to 9.

This morse code uses dots as: . and dashes as: - and uses spaces between letters and / between words. Any unknown characters or morse code will be printed as �. Entering /eng/ followed by English words will force the translation of English to Morse Code, specifically will prevent auto detection of morse code if you only include . and/or – and/or / in your text. Entering /play/ followed by morse code will beep out the morse code. If you only enter /eng/ or /play/, then it will still just translate to morse code. Plus, you can force English translation of commands using /eng/, and if /play/ if followed by text rather than morse code, it will act similar to /eng/, but can’t force Morse Code to English. Also, /play/ is only supported on windows because it uses winsound to beep. Also, enter /end/ to end the program. Lastly, to see these instructions again, enter /help/ or /?/.")
