1st problem :
I tried using merge to matching two csv files below based on album name, so the new csv file will contains the rank, album name, artist name, sales, release date, etc. But only few of the showing up. Then, i tried again using fuzzy wuzzy to match them, but it result in like for example, I have EXO-K MAMA album, it match will EXO OBSESSION album. I attach the code at the end. The release date after matching is also wrong.
