[Python] Appium Calculator Example: No route found for //session

I'm new to appium and looking to try a simple example running against the Windows calculator. I have appium2 running and installed the Windows driver. I see a number of other posts that indicate adding a "/wd/hub" but as far as I can tell that shouldn't be required for Appium 2.

This is the error I keep getting when my python client attempts to connect:

Appium

I see this error on the python side: selenium.common.exceptions.WebDriverException: Message: The requested resource could not be found, or a request was received using an HTTP method that is not supported by the mapped resource

My Python code looks like this:

from appium import webdriver
from appium.options.common import AppiumOptions
from appium.webdriver.common.appiumby import AppiumBy

appium_server_url = "http://172.24.40.154:4723/"

capabilities = {
"platformName":"windows",
"appiumptions": {
"automationName":"Windows",
"deviceName":"WindowsPC",
"app":"Microsoft.WindowsCalculator_8wekyb3d8bbwe!App"
}
}

options = AppiumOptions().load_capabilities(capabilities)
driver = webdriver.Remote(appium_server_url, options=options)
driver.find_element_by_name("One").click()
driver.find_element_by_name("Plus").click()
driver.find_element_by_name("Seven").click()
driver.find_element_by_name("Equals").click()
driver.quit()


How can I fix the error: No route found for //session?
