Python login script returning with status code 419

I have the following python script running to login to a website, the script executes but returns a 419 and doesn't let me login. I think its something to do with the _token parameter or cookies. Is there a way I can get this _token key or generate it programatically.

import requests
import json

url = "https://labhotel.net/"
headers = {
"accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
"accept-encoding" : "gzip, deflate, br",
"Accept-Language" : "en-US,en;q=0.9",

"Referer": "https://labhotel.net/",
}
data = {"_token" :"","username" :"", "password":""}
response = requests.post(url, data=data, headers=headers)

print(response.status_code)
print(response.text)
