Can I use the html <a href></a> tag as a python form submit input type?
In some instances, yes.
Clicking on a hypertext link sends a GET request. The following link and form send similar requests...
<a href="/somescript.php?id=123>Go get it!</a> <form name="form1" method="GET" action="/somescript.php" > <input name="id" type="text" value="123" /> <input type="submit" /> </form>
