# Find the left part of the calendar
start_calendar = driver.find_element(By.CSS_SELECTOR, '.drp-calendar.left')

# Select the desired option value for monthselect
month_select = Select(start_calendar.find_element(By.CSS_SELECTOR, '.monthselect'))
month_select.select_by_value("10") 

# Re-find the start calendar element to avoid StaleElementReferenceException
start_calendar = driver.find_element(By.CSS_SELECTOR, '.drp-calendar.left')

# Find the yearselect element within start_calendar and select the desired option value
year_select = Select(start_calendar.find_element(By.CSS_SELECTOR, '.yearselect'))
year_select.select_by_value("1995")

month_select.select_by_value("10")  year_select.select_by_value("1995") dtermine month and year. Can you determine the week number of the first day of month if month is selected and year is selected?

To determine the week number of the first day of the selected month and year, you can use the datetime module in Python. Here's an example:

```python
import datetime

# Get the selected month and year from the dropdowns
selected_month = int(month_select.first_selected_option.get_attribute("value"))
selected_year = int(year_select.first_selected_option.get_attribute("value"))

# Create a datetime object for the first day of the selected month and year
first_day = datetime.date(selected_year, selected_month, 1)

# Determine the week number of the first day using %U for the week number starting from Sunday
week_number = int(first_day.strftime("%U"))

print("Week number of the first day:", week_number)
```

This code will give you the week number of the first day of the selected month and year.

Perfect! Then determine the day of week of the first day of month

To determine the day of the week for the first day of the selected month and year, you can use the weekday() method from the datetime module. Here's an example:

```python
import datetime

# Get the selected month and year from the dropdowns
selected_month = int(month_select.first_selected_option.get_attribute("value"))
selected_year = int(year_select.first_selected_option.get_attribute("value"))

# Create a datetime object for the first day of the selected month and year
first_day = datetime.date(selected_year, selected_month, 1)

# Use the weekday() method to get the day of the week (0-6, where 0 is Monday and 6 is Sunday)
day_of_week = first_day.weekday()

# Get the name of the weekday using the strftime() method
weekday_name = first_day.strftime("%A")

print("Day of the week of the first day:", weekday_name)
print("Day of the week index:", day_of_week)
```

This code will give you the day of the week for the first day of the selected month and year, both as the weekday name and the weekday index where Monday is 0 and Sunday is 6.

How to select day in calendar with data-title="r0c2"?

To select a day in the calendar with a specific data-title attribute value, such as `r0c2`, you can use the `find_element(By.CSS_SELECTOR, "td[data-title='r0c2']")` method. Here's an example:

```python
# Find the calendar element
calendar = driver.find_element(By.CSS_SELECTOR, '.drp-calendar')

# Find the specific day element with data-title="r0c2"
day_element = calendar.find_element(By.CSS_SELECTOR, "td[data-title='r0c2']")

# Click on the day element to select it
day_element.click()
```

This code will locate the specific day element with the data-title attribute value of `r0c2` in the calendar and click on it to select it. Make sure to adjust the CSS selector accordingly if your specific calendar structure is different.

If I need to change 2 from static numbet to variable day_of_week?

If you need to change the static number `2` to a variable `day_of_week` when selecting the day in the calendar, you can modify the CSS selector to include the variable. Here's an updated example:

```python
import datetime

# Get the selected month and year from the dropdowns
selected_month = int(month_select.first_selected_option.get_attribute("value"))
selected_year = int(year_select.first_selected_option.get_attribute("value"))

# Create a datetime object for the first day of the selected month and year
first_day = datetime.date(selected_year, selected_month, 1)

# Use the weekday() method to get the day of the week (0-6, where 0 is Monday and 6 is Sunday)
day_of_week = first_day.weekday()

# Find the calendar element
calendar = driver.find_element(By.CSS_SELECTOR, '.drp-calendar')

# Find the specific day element with data-title that includes the day_of_week variable
day_element = calendar.find_element(By.CSS_SELECTOR, f"td[data-title='r0c{day_of_week}']")

# Click on the day element to select it
day_element.click()
```

In this updated example, the CSS selector `f"td[data-title='r0c{day_of_week}']"` includes the variable `day_of_week` within an f-string. This will dynamically generate the CSS selector based on the value of `day_of_week`. As a result, it will select the corresponding day element in the calendar based on the day of the week.

See the code

# Find the left part of the calendar
start_calendar = driver.find_element(By.CSS_SELECTOR, '.drp-calendar.left')

# Select the desired option value for monthselect
month_select = Select(start_calendar.find_element(By.CSS_SELECTOR, '.monthselect'))
month_select.select_by_value("10") 

# Re-find the start calendar element to avoid StaleElementReferenceException
start_calendar = driver.find_element(By.CSS_SELECTOR, '.drp-calendar.left')

# Find the yearselect element within start_calendar and select the desired option value
year_select = Select(start_calendar.find_element(By.CSS_SELECTOR, '.yearselect'))
year_select.select_by_value("2021")

Why I need to run this code twice before the following code works?

# Get the selected month and year from the dropdowns
selected_month = int(month_select.first_selected_option.get_attribute("value"))
selected_year = int(year_select.first_selected_option.get_attribute("value"))

The reason that you need to run the code twice before the following code works is because of a common issue called StaleElementReferenceException.

StaleElementReferenceException occurs when an element that was previously located on the page becomes stale or outdated. This can happen when the DOM (Document Object Model) changes, such as when interacting with dropdowns, checkboxes, or other dynamic elements on the page.

In your code, after selecting the month and year in the dropdowns, the DOM is updated, and the original `start_calendar` element becomes stale. Therefore, you need to re-locate the element using the CSS selector `.drp-calendar.left` to find the updated calendar element.

By re-finding the `start_calendar` element after selecting the month and year, you ensure that you have the updated element to retrieve the selected month and year values correctly.

So, running the code twice allows you to refresh the reference to the calendar element and retrieve the selected month and year without running into a StaleElementReferenceException.

What is alternative solution?

One alternative solution to avoid the StaleElementReferenceException is to wait for the element to become stable before trying to retrieve its properties. You can use an explicit wait to wait for the element to be clickable or visible before proceeding with the code. Here's an example:

```python
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Find the left part of the calendar
start_calendar = driver.find_element(By.CSS_SELECTOR, '.drp-calendar.left')

# Select the desired option value for monthselect
month_select = Select(start_calendar.find_element(By.CSS_SELECTOR, '.monthselect'))
month_select.select_by_value("10") 

# Find the yearselect element within start_calendar and select the desired option value
year_select = Select(start_calendar.find_element(By.CSS_SELECTOR, '.yearselect'))
year_select.select_by_value("2021")

# Wait for the month_select and year_select elements to be stable
wait = WebDriverWait(driver, 10)
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '.monthselect')))
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '.yearselect')))

# Get the selected month and year from the dropdowns
selected_month = int(month_select.first_selected_option.get_attribute("value"))
selected_year = int(year_select.first_selected_option.get_attribute("value"))

print("Selected Month:", selected_month)
print("Selected Year:", selected_year)
```

In this alternative solution, we use the WebDriverWait class to wait until the month_select and year_select elements are clickable. This ensures that the elements are stable and ready for interaction before proceeding with retrieving the selected month and year values. Adjust the timeout value as needed in `wait = WebDriverWait(driver, 10)`.

By incorporating this explicit wait, you can avoid the need to re-find the calendar elements and eliminate the StaleElementReferenceException.

what is the kWh cost to charge the batteries on an electric Ford Transit van that is driven 35 kms per day 365 days per year?

To calculate the kWh cost to charge the batteries of an electric Ford Transit van driven 35 km per day for 365 days per year, we need to know the battery capacity of the van in kilowatt-hours (kWh) and the cost of electricity per kilowatt-hour.

Let's assume the battery capacity of the Ford Transit van is 67 kWh (the actual capacity may vary depending on the specific model and year). Now we need the cost of electricity per kWh.

Let's assume the average cost of electricity is $0.12 per kWh (you can look up the cost per kWh on your electricity bill or contact your utility provider for the exact rate in your area).

Now, we can calculate the total energy consumed by the van over the year:
35 km/day * 365 days = 12,775 km
12,775 km * (1 kWh/100 km) = 127.75 kWh

Based on these assumptions, the van would require approximately 127.75 kWh per year.

To calculate the cost:
127.75 kWh * $0.12/kWh = $15.33

So, the estimated cost to charge the batteries of the electric Ford Transit van for a year of driving 35 km per day would be approximately $15.33 assuming a battery capacity of 67 kWh and an electricity cost of $0.12 per kWh.

Отправка JSON уведомления партнеру о результате перевода.
Отправлять при получении сообщения C2B_SBP_SEND_NOTIFICATION через rabbit. Напиши пример для spring boot

Для отправки JSON уведомления о результате перевода партнеру при получении сообщения `C2B_SBP_SEND_NOTIFICATION` через RabbitMQ в Spring Boot, вы можете использовать следующий пример:

1. Создайте класс, представляющий JSON уведомление. Допустим, у вас есть класс `Notification`:

```java
public class Notification {
    private String orderId;
    private String status;
    // другие поля уведомления

    // геттеры и сеттеры
}
```

2. Создайте слушатель для RabbitMQ, который будет слушать сообщения с типом `C2B_SBP_SEND_NOTIFICATION` и отправлять JSON уведомление партнеру. Например, создайте класс `NotificationListener`:

```java
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.messaging.handler.annotation.Payload;
import org.springframework.stereotype.Component;

@Component
public class NotificationListener {

    @RabbitListener(queues = "notificationQueue")
    public void processNotification(@Payload Notification notification) {
        // Отправка JSON уведомления партнеру
        // В этом примере просто выводим уведомление в консоль
        System.out.println("Received notification: " + notification);
    }
}
```

3. В файле `application.properties` настройте подключение к RabbitMQ:

```properties
spring.rabbitmq.host=your-rabbitmq-host
spring.rabbitmq.port=your-rabbitmq-port
spring.rabbitmq.username=your-rabbitmq-username
spring.rabbitmq.password=your-rabbitmq-password
```

4. Создайте конфигурацию RabbitMQ для Spring Boot. Например, создайте класс `RabbitMQConfig`:

```java
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RabbitMQConfig {

    @Bean
    public Queue notificationQueue() {
        return new Queue("notificationQueue");
    }
}
```

5. Теперь, когда вы получите сообщение с типом `C2B_SBP_SEND_NOTIFICATION`, он будет отправляться на очередь `notificationQueue`, и слушатель `NotificationListener` будет обрабатывать уведомление.

Обратите внимание, что в этом примере JSON уведомление просто выводится в консоль. Вам потребуется адаптировать код в методе `processNotification` для фактической отправки JSON уведомления партнеру.

а где в коде указано, что я слушаю сообщение C2B_SBP_SEND_NOTIFICATION?

В приведенном примере кода рассмотрим, что сообщение с типом `C2B_SBP_SEND_NOTIFICATION` является частью передаваемого объекта `Notification`. Поэтому слушатель `NotificationListener` будет слушать сообщения из очереди `notificationQueue` и автоматически десериализовывать его в объект `Notification`.

Чтобы указать, что слушатель будет прослушивать только сообщения с типом `C2B_SBP_SEND_NOTIFICATION`, вы можете добавить аргумент аннотации `@RabbitListener` с указанием значения `bindings` и `MessageListenerAdapter`:

```java
@RabbitListener(bindings = @QueueBinding(
        value = @Queue(value = "notificationQueue", durable = "true"),
        exchange = @Exchange(value = "your-exchange", type = "direct"),
        key = "C2B_SBP_SEND_NOTIFICATION"))
public void processNotification(@Payload Notification notification) {
    // Отправка JSON уведомления партнеру
    // В этом примере просто выводим уведомление в консоль
    System.out.println("Received notification: " + notification);
}
```

Здесь `your-exchange` - это имя вашей биржи, а `"C2B_SBP_SEND_NOTIFICATION"` - ключ маршрутизации сообщений.

Обратите внимание, что в этом примере мы использовали `direct`-тип биржи, который маршрутизирует сообщения только с указанными ключами. Если вы используете другой тип биржи, вам может потребоваться изменить настройки маршрутизации на свои конкретные требования.
