Итерация нескольких циклов for на основе одного и того же списка

/ 03 октября 2018

В моем шаблоне django мне нужно добавить две петли на основе одного и того же сжатого списка.К сожалению, кажется, что выполняется только первый цикл.

У меня есть следующий код в views.py:

@login_required
def edit_doctorslots(request, cliniclabel, doctor_id):
    doctor_id=int(doctor_id)
    doc = get_object_or_404(doctor, docid=doctor_id)
    cl = Clinic.objects.get(label=cliniclabel)
    print("Clinic name", cl.name)
    formslot = SlotForm()
    formspecialdays = SpecialdaysForm()
    formweekdays = WeekdaysForm()
    weekdays = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']
    weekdaynum = [0,1,2,3,4,5,6]
    weekzip = zip(weekdays, weekdaynum)
    newweekzip = weekzip
    return render(request, 'clinic/editslots.html', {'rnd_num': randomnumber(), 'clinic': cl, 'doctor': doc, 'formslot': formslot, 'formspecialdays': formspecialdays, 'formweekdays': formweekdays, 'weekzip': weekzip, 'newweekzip': newweekzip })

Мой шаблон: 

<div class="container ml-5 mr-5">
    <div class="jumbotron slotgroup slotavailable mb-1 mt-5" id="jumbo_week_avail">
      <div class="slot-header" role="alert">
        Enter your weekly consultation hours at {{ clinic.name }}. This will supercede regular hours. If you specify some week days, but not others, you will be assumed to be on leave during those days. If you dont specify any week days, but specify regular hours, you will be assumed to be working on all days.
      </div>
      {% for weekday, weeknum in weekzip %}

В Python 3 zip возвращает генератор: после итерации он исчерпан.Сначала вы должны преобразовать его в список: 

weekzip = list(zip(weekdays, weekdaynum))
...
