How to minify inline javascript with Python

Question

The answers that I get only cover .js files but I need to minify something like this:

<script>
    window.addEventListener('load', function (e)
    {
        ...
    });
</script>

To this:

<script>window.addEventListener('load',function(e){...});</script>

Actually I use "htmlmin" to minify the HTML code before I write the files with it but the inline javascripts remain with the original format.

Any help what to do here? Maybe a new package to replace "htmlmin". Thanks in advance.

Using REST API from the site https://www.minifier.org/.

Example here:

from bs4 import BeautifulSoup
import requests
import json

url = 'https://minify.minifier.org/'

data = """<script>
    window.addEventListener('load', function (e)
    {
        i = 4;
    });
    </script>
"""

soup = BeautifulSoup(data, 'lxml')
script = soup.select_one('script')
r = requests.post(url, data={"source":script.text, "type" :"js"})
json_data = json.loads(r.text)
script.clear()
script.append(json_data['minified'])

print(script)

It prints:

<script>window.addEventListener('load',function(e)
{i=4})</script>
