"AccountNo": "", };
var options = {
'method' : 'post',
'contentType': 'application/x-www-form-urlencoded; charset=UTF-8',
// Convert the JavaScript object to a JSON string.
'payload' : JSON.stringify(data),
'muteHttpExceptions': true,
};
var res = UrlFetchApp.fetch(url,options)
var cont = res.getContentText()
Logger.log(cont)
}

On the python code you are doing 2 requests, a GET and a POST
Since they are within a Session object cookies returned by the website are being automatically managed.
That concept however does not exist in built-in libraries of Apps Script, given that it has to be done manually.
Sample Code:
function myFunction() {
// =================== GET ===================
//initiating a request object for the first GET request
var request1 = {
'url': 'https://billing.te.eg/ar-eg',
'method' : 'get',
'muteHttpExceptions': true,
'validateHttpsCertificates': false,
};
// Adding ('validateHttpsCertificates': false,) since it is the equivalent of (verify=false) in the python code
var resGet = UrlFetchApp.fetchAll([request1]); //storing the response to digest cookies
// Digesting the cookies returned by the server (excluding cookies attributes) and adding them to an array to be reused in the POST
var cookies = [];
for (response of resGet) {
var headers = response.getAllHeaders();
for (cookie of headers['Set-Cookie']){
cookies.push(cookie.split(";")[0]);
}
}
// =================== POST ===================
// declaring the payload for the POST
var postData = {
"AreaCode": "055",
"PhoneNumber": "3020100",
"PinCode": "",
"InquiryBy": "telephone",
"AccountNo": "",
};
//Initiating a request object for the POST request and injecting the stored cookies into the HTTP headers
var request2 = {
'url': "https://billing.te.eg/api/Account/Inquiry",
'method' : 'post',
'contentType': 'application/x-www-form-urlencoded',
'muteHttpExceptions': true,
'validateHttpsCertificates': false,
'headers' : {
'Cookie': (cookies.join("; ") + ";"),
},
'payload' : postData,
};
//Storing the POST response
var resPost = UrlFetchApp.fetchAll([request2]);
//Printing POST response content to console
console.log(resPost[0].getContentText());
}
