Create Shared Access Signature in Python - Azure Api Rest Management

Question

sorry for my english.

I'm interacting with the Azure admin rest API and I want to programmatically create a SAS token. In Azure documentation is explained for C # (I attach the code below) but I need to implement it in Python (I'm new) and I can't get the data encoding and signing process correctly, even though I've searched a lot of information and tested in some different ways. Could someone help me to "translate" this code?. Thank you very much.

c#

using System;   
using System.Text;   
using System.Globalization;   
using System.Security.Cryptography;   
  
public class Program   
{   
    public static void Main()   
    {   
        var id = "account-name";   
        var key = "account-key";   
        var expiry = DateTime.UtcNow.AddDays(10);   
        using (var encoder = new HMACSHA512(Encoding.UTF8.GetBytes(key)))   
        {   
            var dataToSign = id + "\n" + expiry.ToString("O", CultureInfo.InvariantCulture);   
            var hash = encoder.ComputeHash(Encoding.UTF8.GetBytes(dataToSign));   
            var signature = Convert.ToBase64String(hash);   
            var encodedToken = string.Format("SharedAccessSignature uid={0}&ex={1:o}&sn={2}", id, expiry, signature);   
            Console.WriteLine(encodedToken);   
        }   
    }   
}

Finally I can create the SAS token. Here is the code for the signature:

string_to_sign = '{}{}{}'.format(id_azure,'\n',expiry)

signature = (base64.b64encode(hmac.new(bytearray(key_azure, "utf-8") , bytearray(string_to_sign,"utf-8") , hashlib.sha512).digest())).decode("utf-8").replace("\n", "")
