Problem $1.$ The two files contain records on some of the same people, but there are people in df$1$ that are not in df$2($and vice versa$).$ Your first task is to create a new dataframe called df that contains $(1)$ the columns from both df$1$ and df$2,$ but $(2)$ only the names that belong to both df$1$ and df$2.$ Hint: what we're doing here is called an "inner join"; it takes the intersection of values in the "name" column, which is shared in both DataFrames. Take a look at the function pd$.$merge. There is also more information on DataFrame joining and merging.
