Automate purchases of items from a website in Python

project description: I would like a method that takes in a map of information (email address ,credit card, message, log in, etcetc), and uses this information to navigate to the appropriate target ecommerce cart page, and navigates through to purchase the item The program will need to control either firefox or chrome or internet explorer, and input the information directly via the browser (this is so that the end user can sometime pause and modify information directly in the browser). This means it should be visible to the human what is being inputted, and where. The total flow is 3-12 pages, dependent on certain warranty pages, shipping address correction pages, if you are already logged in, etc There will be a large number of follow-on projects to this, and so it will make sense to design some of the parts of this modularly (ie, filling in the login screen, entering the credit card info screen ,etc) please let me know the python version and packages you plan to use before beginning. most packages will likely work
