Multiplying between two values

[doug2019]

I need an equation in Python that gives me the values ​​that can be multiplied, since they must be less than 10. Only they must have one decimal place before, like 0.1. That's what I'm having a problem for coding.

For example: T = x . y

x = [1,2,3,4,5] and y = [10,5,3.33,2.5,2]
