各位大神帮我看看这一段有什么问题，谢谢啦！
VS 2017中views.py
from django.shortcuts import render
from django.http import HttpResponse
def pylinkweb(request):
return HttpResponse("Django 让 python 能方便连接网页")
def deposits(request):
return render(request,'E_10_1.html',{})
def result(request):
pv=int(request.GET['amount'])
i=float(request.GET['rate'])
n=int(request.GET['period'])
fv=str(round(pv*((1+i)**n),2))
return HttpResponse(fv)
