python - 使用 session 的Django View 中 “def”的语法错误

Question

它位于Django项目中的应用程序中，位于该应用程序的views文件中。该应用程序安装在settings.py中，但在调用 View 之前会引发错误。

我在CouponForm的“def”中的“f”处遇到错误，它说这是一个SyntaxError，但我无法解决问题。 urlconf仅引用manageCoupons函数。
在此先感谢您的帮助!

views.py:

from models import Coupon
from django.shortcuts import render
from django.http import HttpResponse

def CouponList(req):
    c = Coupon.objects.all()
    return render(req,'coupon_list.html',{'title':'Coupons','coupons':c}

def CouponForm(req1):
    if 'name' in req1.GET and 'desc' in req1.GET:
        name1 = req1.GET['cname']
        desc = req1.GET['desc']
        c = Coupon(name=name1, description=desc)
        c.save()
        success = True
    else:
        success = False
    return render(req1,'coupon.html',{'title':'New Coupon','success':success,})

def CouponDelete(req2):
    if 'name' in req2.GET:
        name1 = req2.GET['name']
        c = Coupon.objects.filter(name=name1)
        c.delete()
        success = True
    else:
        success = False
    return render(req2,'coupon_delete.html',{'title':'Delete Coupon','success':success}


def manageCoupons(request):
    if 'passwrd' in request.GET:
        psswrd = request.GET['passwrd']
        if psswrd == 'password0':
            return CouponList(request)
        elif psswrd == 'password1':
            request.session["function"] = 'cform'
            return CouponForm(request)
        elif psswrd == 'password2':
            request.session["function"] = 'cdelete'
            return CouponDelete(request)
    elif "function" in request.session:
        if request.session["function"] == 'cdelete':
            return CouponDelete(request)
        elif request.session["function"] == 'cform':
            return CouponForm(request)
    else:
        return HttpResponse("<a href='/'>Home</a>")

def CouponList(req):
    c = Coupon.objects.all()
    return render(req,'coupon_list.html',{'title':'Coupons','coupons':c})
                                                                        ^
                                                                        |
                                                              You are missing this bracket
