recursion task

[scorp08]

Hello ALL
I have a following :

limits=[(1,9,1,"v"),(50,350,50,"d")]
for i in range(len(limits)):

    begin=limits[i][0]
    end=limits[i][1]
    increment=limits[i][2]

I want to get a list of list like

  [[1,50],[1,100],[1,150]...,[2,50],[2,100]..]   

like combination of all values from begin to end values.
How can I do it with recursion ?
Thnks for help
