Hello I tested your code and seems like the website doesnt load the data until a browser requests the information. Since you are using the requests modules there is no browser.
You need to use a browser emulator like the selenium module to get that data.
This module will open a browser for you and you can program it to navigate to that website wait until everything gets loaded and get the information for you.
Steps:
1-Install selenium
2-Download the chromedriver and put it somewhere (maybe in your project)
https://chromedriver.chromium.org/downloads
3-Learn selenium (this is an amazing tool to automate navigation of the web). This is an untested example just so you can get an idea (might work for you right away but might not)
import time
from selenium import webdriver
driver = webdriver.Chrome('/path/to/chromedriver') # Change this to your chromedriver path.
driver.get('https://www.suncalc.org/#/12.98,80.188,10/2020.02.21/15:51/1/3');
time.sleep(5) # Let the user actually see something!
clickSunrise = driver.find_element_by_id('clickSunrise')
print(clickSunrise.text)
I hope this helps!
