How can I login using python selenium?

Question

I am trying to login to https://www.crowdmed.com/login using selenium.

This is the code I have so far. I am unable to login with my credentials. The error says "lable is not reachable by keyboard. When I try to use the name or id of the div, I get the error saying no such element found.

url ='https://www.crowdmed.com/case-selection?showCase=92447'
# This is what I really want to scrape
driver = webdriver.Firefox()
driver.get(url)

label = driver.find_element_by_xpath('//label["Email:"]')
#username = driver.find_element_by_name('Username')
#password = driver.find_element_by_id("password")
password = driver.find_element_by_xpath('//label["Password:"]')
label.send_keys("username")
password.send_keys("password")

driver.find_element_by_name("submit").click()

The corresponding error is

When I try accessing by name or id as suggested on some other posts ( with the commented lines in my post), I get the following error. I have tried various combinations of "user", User" "username", "Username".

NoSuchElementException: Message: Unable to locate element: [name="Username"]

You are using a wrong expression.
Generally //label["Email:"] is not a valid XPath expression.
To correctly and uniquely locate the username input field you can use something like this:

//div[@class="page-content"]//input[@ng-model="username"]

So your code line could be

username_input = driver.find_element_by_xpath('//div[@class="page-content"]//input[@ng-model="username"]')

You are also missing a wait there to make the page loaded before ayou going to access the elements there.
To do so it's recommended to use Expected Conditions explicit waits.
With it your code will be something like this:

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

url ='https://www.crowdmed.com/case-selection?showCase=92447'
# This is what I really want to scrape
driver = webdriver.Firefox()
wait = WebDriverWait(driver, 20)

driver.get(url)

username_input = wait.until(EC.element_to_be_clickable((By.XPATH, '//div[@class="page-content"]//input[@ng-model="username"]')))

username_input.send_keys(username)

You can combine the 2 last lines in 1 by:

wait.until(EC.element_to_be_clickable((By.XPATH, '//div[@class="page-content"]//input[@ng-model="username"]'))).send_keys(username)
