If-statement in Generate Attributes

Hello Community,

I have a school/university project and I'm stuck. I also never really programmed but tried to search here and on Google and couldn't find a usefull (at least for me) solution.

The structure is the following:
T1Name T1Tag T2Name T2Tag ... T146Name T146Tag
x             a          y             b             x                 a
y             b          x             a             y                 b

I want to write an if statement within the Generate Attributes Function, if T* Tag=a then it should generate a new attribute with the Name given in T*Name. But I don't know how I can write that in Code.

I'm thankfull for every help!
Thanks
