Using the python 'Requests' module for a POST request, getting the response as if it were GET

Question

So, I am trying to make a script that checks for bus redundancy. The source link for this is https://reservation.pc.gc.ca/ .

In the backup unit, you must select the following:

• Reservation: daily use (guided tours, Lake OHara bus).
• Park: Yoho Lake O'Hara
• Arrival Date: June 16
• Lot Size: 2

When these parameters are entered, you will go to the following page: https://reservation.pc.gc.ca/Yoho-LakeO'Hara? The calendar

I understand that if I send a POST request to this second link with the correct data, it should return the page I'm looking for

If I look in the dev network information settings, when I select the correct parameters, the form data:

__ EventTarget:

__ EVENTARGUMENT: __VIEWSTATE: - full string length -

__ VIEWSTATEGENERATOR: 8D0E13E6

ctl00 $ MainContentPlaceHolder $ rdbListReservationType: Events

ddlLocations: 213a1bc9-9218-4e98-9a7f-0f209008e437 **

ddlArrivalMonth: 2017-06-16

ddlArrivalDay: 19

ddlNights: 1

ddlDepartureMonth:

ddlDepartureDay:

ddlEquipment:

ddlEquipmentSub:

ddlPartySize: 2

ctl00 $ MainContentPlaceHolder $ chkExcludeAccessible: on

ctl00 $ MainContentPlaceHolder $ imageButtonCalendar.x: 64

ctl00 $ MainContentPlaceHolder $ imageButtonCalendar.y: 56
