Python Pandas merge only certain columns

Question

Is it possible to only merge some columns? I have a DataFrame df1 with columns x, y, z, and df2 with columns x, a ,b, c, d, e, f, etc.

I want to merge the two DataFr

Answer 1

You could merge the sub-DataFrame (with just those columns):

df2[list('xab')]  # df2 but only with columns x, a, and b

df1.merge(df2[list('xab')])
