I have this data:
I wanted to compare A and B for matches not by row but rather search A0 if it is in column B and so on. Moreover, I wanted to ignore the .AX in column A because it would not find any matches in column B anyway.
I used this, but it matches values row by row and it returns False or True. I would like to print the matches in a new Column C:
df3['match'] = df3.A == df3.B
