Demonstrate the simplicity which walrus operator provides when writing a while loop

# Longer version without walrus operator
digit_list = []
user_input = input('Type anything other than digits, and this prompt will quit: ')
while user_input.isdigit():
    digit_list.append(user_input)
    user_input = input('Type anything other than digits, and this prompt will quit: ')

print('The digits entered by user are: ', digit_list)

# Shorter version using walrus operator

    digit_list.append(user_input)

print('The digits entered by user are: ', digit_list)
