Ok,  so I've looked around on how to do this and haven't really found an answer that showed me examples that I could work from. 
What I'm trying to do is have a script that can do things like:
-Log into website
-Fill out forms or boxes etc.
Something simple that might help me in that I though of would be for example if I could write a script that would let me log into one if those text message websites like textnow or something like that,  and then fill out a text message and send it to myself.  
If anyone knows a good place that explains how to do something like this,  or if anyone would be kind enough to give some guidance of their own then that would be greatly appreciated.
So after some good answers and further research,  I have found that selenium is the thing that best suits my needs.  It works not only with python,  but supports other languages as well. If anyone else is looking for something that I had been when I asked the my question, a quick Google search for "selenium" should give them all the information they need about the tool that I found best for what I needed.
