Present me some Python code

import stripe
from django.conf import settings
from django.contrib.auth.decorators import login_required
from django.shortcuts import render, redirect
from django.urls import reverse
from .fashions import Subscription

stripe.api_key = settings.STRIPE_SECRET_KEY

@login_required
def subscription_plans(request):
    # Fetch accessible subscription plans from Stripe
    plans = stripe.Plan.listing()
    return render(request, 'subscriptions/subscription_plans.html', {'plans': plans})

@login_required
def create_subscription(request, plan_id):
    consumer = request.consumer
    plan = stripe.Plan.retrieve(plan_id)

    # Create a subscription on Stripe
    subscription = stripe.Subscription.create(
        buyer=consumer.stripe_customer_id,  # Assuming you retailer buyer IDs
        gadgets=[{'plan': plan.id}],
        payment_behavior='default_incomplete',  # Change based mostly in your necessities
        broaden=['latest_invoice.payment_intent']
    )

    # Save subscription particulars to your database
    Subscription.objects.create(
        consumer=consumer,
        subscription_id=subscription.id,
        plan_id=plan.id,
        standing=subscription.standing,
        current_period_start=subscription.current_period_start,
        current_period_end=subscription.current_period_end
    )

    return redirect(reverse('subscription_success'))

# webhook_handlers.py
from django.http import HttpResponse
import json
import stripe
from django.conf import settings

stripe.api_key = settings.STRIPE_SECRET_KEY

def handle_subscription_webhook(request):
    payload = request.physique
    occasion = None

    attempt:
        occasion = stripe.Occasion.construct_from(
            json.hundreds(payload), stripe.api_key
        )
    besides ValueError as e:
        # Invalid payload
        return HttpResponse(standing=400)

    # Deal with particular occasions
    if occasion.sort == 'bill.payment_failed':
        # Deal with cost failure
        # Replace consumer's subscription standing or take obligatory actions

    return HttpResponse(standing=200)
