Is there a way to get js display data using the requests python module?

Question

So I am trying to access data on a video game stat tracker website. Now when I go to inspect element on the website and look at the code it says:

<div class="trn-defstat__value">Division 7</div>

But when I use requests.get(url).text the same element shows up as:

<div class="trn-defstat__value">{{ activeArena.division.metadata.description }}</div>

I am trying to get the "Division 7" part but keep getting this activeArena thing, I am using python, the code I have tried is

import requests
url = ('https://fortnitetracker.com/profile/all/tl%20starrlol/competitive?season=16')
file = open("myfilename", "w")
r = requests.get(url)
info = r.content
info = str(info)
file.write(info)
file.close()

and I have also tried

import requests
url = ('https://fortnitetracker.com/profile/all/tl%20starrlol/competitive?season=16')
file = open("myfilename", "w")
r = requests.get(url)
info = r.text
file.write(info)
file.close()

I am pretty new to coding so if the answer is obvious I apologize, but I am lost.

The HTML you're receiving contains a template engine code, the javascript on the page is loading and filling it up with values. If you examine the page via the network panel on the browser you'll notice a stats API call. Make the same call from your code to extract the data you need.

import requests

url = "https://fortnitetracker.com/api/v0/profile/863f1c3c-2e61-487e-8987-ceefff2981ad/stats"
querystring = {"season":"16","isCompetitive":"true"}
response = requests.request("GET", url, data="", headers={}, params=querystring)

data = response.json()
print (data[0]['arena']['division']['displayValue'])

# prints "Contender League Division 7"

It's better to check for official APIs instead of this approach. The parameters in the API like the UUID after profile may be a parameter that's valid only for a certain time. It's also worth evaluating the Selenium or Puppeteer approach recommended in the comments(under the question) to see if that fits your overall problem.
