I'm working on a simple web app using flask and I added a simple rating system using the select tag. My question is how I go to another route once the user select a number from the dropdown menu and also know which number they choosed.

<label class="custom-select">
Give your rate
<select class="custom-select" 
style="width:200px;" id="example">
 <option value="1">1</option>
<option value="2">2</option> <option 
value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</label>
