Automatically fill in forms on line

Dear all,

I want to automatically complete the following task:

1. Go to http://www.ffiec.gov/Geocode/default.aspx;
2. Fill in an address in the form "Street Address:" . e.g. "1316 State
Highway 102";
3. Fill in a ZIPcode in the form "Zip Code:" . e.g. "04609";
4. Click the bottom "search";
5. In the opened page, extract and save the number after "Tract Code".
In the example, it will be "9659".
6. Repeat Step 1 with a new address.

Can Python realize these steps? Can these steps be done witout
openning and IE windows? Especially, I dont know how to write code for
step 2, 4 and 5.

Thank you!
.
