Autowire String parameter in symfony

How can I wire a String parameter in Symfony 3.4?

I have simple service and I want to wire a url parameter specified in parameters.yml:

namespace AppBundle\Service;

use Psr\Log\LoggerInterface;

class PythonService {

    private $logger;
    private $url;

    /**
     * @param LoggerInterface $logger
     * @param String $url
     */
    public function __construct(LoggerInterface $logger, String $url) {
        $this->logger = $logger;
        $this->url = $url;
    }
}

My service.yml looks like:

AppBunde\Services\PythonService:
    arguments: ['@logger', '%url%']

But I am getting error:

Cannot autowire service "AppBundle\Service\PythonService": argument "$url" of method "__construct()" is type-hinted "string", you should configure its value explicitly.

I tried also manually specify parameters:

AnalyticsDashboardBunde\Services\PythonService:
    arguments:
        $logger: '@logger'
        $url: '%session_memcached_host%'

This gives me following error:

Invalid service "AppBundle\Services\PythonService": class "AppBundle\Services\PythonService" does not exist.

First, you have a typo in AppBundle\Services\PythonService (Services <> Service).

Then, string <> String. No uppercase in php.

You can bind an argument to a certain parameter/service:

service.yml:

services:
    _defaults:
        bind:
            $memcacheHostUri: '%session_memcached_host%'

Service class: (have to be the same var name as specified ^)

public function __construct(LoggerInterface $logger, string $memcacheHostUri)

Controller action:

public function myAwesomeAction(PythonService $pythonService)
{
    $pythonService->doPythonStuffs();
}

With this solution, if you create others services which need the memecacheHostUri, it will be autowired for these services too.

    //    services.yml
    app.python_service:
    class: AppBundle\Service\PythonService
    arguments:
        $logger: '@monolog.logger.request'
        $url: 'link'
    public: true

     //   in controller
    //use container:
    $pS = $this->container->get('app.python_service');
