bug in django tutorial

[DoyunKim]

there is a bug in html source at django tutorial
​https://docs.djangoproject.com/ko/4.1/intro/tutorial04/
at this example

<h1>{{ question.question_text }}</h1>

<ul>
{% for choice in question.choice_set.all %}
    <li>{{ choice.choice_text }} -- {{ choice.votes }} vote{{ choice.votes|pluralize }}</li>
{% endfor %}
</ul>

<a href="{% url 'polls:detail' question.id %}">Vote again?</a>

{{ choice.choice_text }} -- {{ choice.votes }}

this code should be changed to below

{{ choice.choice_text }} - {{ choice.votes }}

I'm not aware of any reason why using a double dash there is inappropriate.
