[Python] Compare 2 lists

Hello,

I'm new to the python programming, and I have a question.
I have to write a program that prints a receipt for a restaurant. The input is a list which looks like:

Code:
product1
product3
product8
....

In the other input file there is a list which looks like:

Code:
product1 coffee 5,00
product2 bread 7,50
....

So I need to compare the first list to the second and print the receipt with prices and a total price.

It doesn't look that hard but I just don't know how or where to start. Can somebody help me?

Thank you

NAME
isympy - interactive shell for SymPy SYNOPSIS
isympy [-c | --console] isympy [ {-h | --help} | {-v | --version} ] DESCRIPTION
isympy is a Python shell for SymPy. It is just a normal python shell (ipython shell if you have the ipython package installed) that exe- cutes the following commands so that you don't have to: >>> from __future__ import division >>> from sympy import * >>> x, y, z = symbols("xyz") >>> k, m, n = symbols("kmn", integer=True) So starting isympy is equivalent to starting python (or ipython) and executing the above commands by hand. It is intended for easy and quick experimentation with SymPy. For more complicated programs, it is recommended to write a script and import things explicitly (using the "from sympy import sin, log, Symbol, ..." idiom). OPTIONS
-c shell, --console=shell Use the specified shell (python or ipython) as console backend instead of the default one (ipython if present or python otherwise). Example: isympy -c python FILES
${HOME}/.sympy-history Saves the history of commands when using the python shell as backend. BUGS
The upstreams BTS can be found at <http://code.google.com/p/sympy/issues/list> Please report all bugs that you find in there, this will help improve the overall quality of SymPy. SEE ALSO
