Copying random text from a notepad file in Python

I'm trying to write a python script to fill out a web form, submit it, and then repeat the process.

Now I have a .txt file which has text which is to be entered into the text fields onto the page. For example, I have a field named "Title", so I want my script to randomly select any one of the titles that I have in my text file and fill that particular field with that.

Here's the web form I'm trying to fill I only need to fill a few of the fields on the given page, like title, description etc. and upload a photo also. If you'll see the page you'll get the idea of what I'm talking about.

Any ideas on how I can go about with this?
