How to save all windows.beep sound in a wav file python

Question

I want to save all beep sound i wav file,i came across sf.write function but dont know how to use.

import time
import winsound
import soundfile as sf
freq = 550  # Hz
dotLength = 60  # milliseconds
dashLength = dotLength * 3
pauseWords = dotLength * 7
print("hi ji")
alphaToMorse = {'a': ".-", 'b': "-...", 'c': "-.-.", 'd': "-..", 'e': ".",
                'f': "..-.", 'g': "--.", 'h': "....", 'i': "..", 'j': ".---", 'k': "-.-",
                'l': ".-..", 'm': "--", 'n': "-.", 'o': "---", 'p': ".--.", 'q': "--.-",
                'r': ".-.", 's': "...", 't': "-", 'u': "..-", 'v': "...-", 'w': ".--",
                'x': "-..-", 'y': "-.--", 'z': "--..",
                '1': ".----", '2': "..---", '3': "...--", '4': "....-", '5': ".....",
                '6': "-....", '7': "--...", '8': "---..", '9': "----.", '0': "-----",
                ' ': "/", '.': ".-.-.-", ',': "--..--", '?': "..--..", "'": ".----.",
                '@': ".--.-.", '-': "-....-", '"': ".-..-.", ':': "---...", ';': "---...",
                '=': "-...-", '!': "-.-.--", '/': "-..-.", '(': "-.--.", ')': "-.--.-",
                'á': ".--.-", 'é': "..-.."}

morsecode()

I tried sf.write() function but dint know how to.Can you help me change the code to get the required wav file.the functions are simply creating and playing a morse which i want to save in wav file.The fuctions morseaudio(morse) converts it in morse code data.
