Hi @Mubsi

I get all three tests failed even though the interactions appended structure seems correct.

Can you please help.

Thanks.

Hi @getjaidev,

For your Ex 4, your issue lies in the variable feature_i_j_name. You are not using the right operator.

Please pay close attention to the code cell instruction:

# create the name of the interaction feature by combining both names
# example: "apple" and "orange" are combined to be "apple_x_orange"

Best,
Mubsi

Thank you, it ended up being a problem of not using the variable m in the loop (i calculated the loop range when i called it instead)
