recursion task

[buran]

please, post the code as one block with proper indentation. If you want to comment specific line - use python comments.
It's difficult to understand what you have and what you want to achieve. e.g. what is i?

not recursion (don't see the need for it or how you would use it anyway), probably something like

import itertools
limits=[(1,9,1,"v"),(50,350,50,"d")]
print(list(itertools.product(range(*limits[0][:-1]), range(*limits[1][:-1]))))

Output:
[(1, 50), (1, 100), (1, 150), (1, 200), (1, 250), (1, 300), (2, 50), (2, 100), (2, 150), (2, 200), (2, 250), (2, 300), (3, 50), (3, 100), (3, 150), (3, 200), (3, 250), (3, 300), (4, 50), (4, 100), (4, 150), (4, 200), (4, 250), (4, 300), (5, 50), (5, 100), (5, 150), (5, 200), (5, 250), (5, 300), (6, 50), (6, 100), (6, 150), (6, 200), (6, 250), (6, 300), (7, 50), (7, 100), (7, 150), (7, 200), (7, 250), (7, 300), (8, 50), (8, 100), (8, 150), (8, 200), (8, 250), (8, 300)]
