I am looking for help with dataframe manipulation. I currently have the GWAS catalog in a dataframe (pictures below) and I need to make it so that I can filter all the information where the column DISEASE/TRAIT has the value of "Alzheimer's disease". That being said, I don't know how to move these rows that contain this value in that column into a separate data frame so I can do data visualization on it.

This is what I have for setting the first data frame and the print statement to find the Alzheimer's disease attribute, but I cannot figure out how to move it into it's own data frame containing those 265 rows.
