NoReverseMatch - Reverse for 'emotion-buttons' with arguments '(1,)' not found. 1 pattern(s) tried: ['student/emotion\\-buttons$']

I keep getting this error message "NoReverseMatch at /student/take-exam/1

Reverse for 'emotion-buttons' with arguments '(1,)' not found. 1 pattern(s) tried: ['student/emotion\-buttons$']'".

I have been unable to figure out the problem with my code. When I link take_exam to start_exam it works fine, so the problem should be in linking emotion_buttons to start_exam.

Here is what I have so far:

urls.py

from django.urls import path
from student import views
from django.contrib.auth.views import LoginView

urlpatterns = [
path('student-exam', views.student_exam_view,name='student-exam'),
path('take-exam/<int:pk>', views.take_exam_view,name='take-exam'),
path('emotion-buttons', views.emotion_buttons_view,name='emotion-buttons'),
path('start-exam/<int:pk>', views.start_exam_view,name='start-exam'),
]

views.py

@login_required(login_url='studentlogin')
@user_passes_test(is_student)
def take_exam_view(request,pk):
    course=QMODEL.Course.objects.get(id=pk)
    total_questions=QMODEL.Question.objects.all().filter(course=course).count()
    questions=QMODEL.Question.objects.all().filter(course=course)
    total_marks=0
    for q in questions:
        total_marks=total_marks + q.marks
    
    return render(request,'student/take_exam.html',{'course':course,'total_questions':total_questions,'total_marks':total_marks})



@login_required(login_url='studentlogin')
@user_passes_test(is_student)
def start_exam_view(request,pk):
    course=QMODEL.Course.objects.get(id=pk)
    questions=QMODEL.Question.objects.all().filter(course=course)
    if request.method=='POST':
        pass
    response= render(request,'student/start_exam.html',{'course':course,'questions':questions})
    response.set_cookie('course_id',course.id)
    return response


@login_required(login_url='studentlogin')
@user_passes_test(is_student)
def emotion_buttons_view(request):
   courses=QMODEL.Course.objects.all()
   return render(request,'student/emotion_buttons.html',{'courses':courses})

take_exam.html

<a href="{% url 'emotion-buttons' course.id %}" class="btn btn-info">Let's Start</a>

emotion_buttons.html

<a href="{% url 'start-exam' %}" class="btn btn-info">End Session</a>

Any help would be appreciated
