def ascii_str(lst):
    text = ""
    for num in lst:
        text = text + chr(num)
    return text

try:
    decide = int(input("Press 1 to change String to ASCII.\nPress 2 to change ASCII to String : "))


    if decide == 1:
        usr_str = input("Enter your string : ")
        res = str_ascii(usr_str)
        print("ASCII values : ", res)

    elif decide == 2:
        ascii_list = [int(num) for num in input("Enter ASCIIs values saperated by , : ").split(",")]
        res = ascii_str(ascii_list)
        print("String : ", res)
