<OT topic="HTTP">
If the script has side-effects (adding/updating/deleting database 
records, writing files, etc), the script should not "output results", 
but redirect to another url where the user can see these results.

Else - if the script doesn't have side-effects (ie :a search form, ...), 
then the HTTP method should be "GET", not "POST".

<OT topic="HTML">
button elements don't submit the form - they in fact don't do anything 
unless you attach behaviour to them with javascript. What you want here 
is an input type='submit'.

Also, the "button" tag doesn't require a end tag.

<form method="POST" action="/cgi-bin/script.py" name="coord">
<label for="data1">Entre com os dados</label>
<input type="text" name="data1" id="data1"><br>

<label for="data2">Entre com os dados </label>
<input type="text" name="data2" id="data2"><br>
Vai magraum <input type="submit" name="submete">
</form>
