move column in pandas dataframe

Question

I have the following dataframe:

   a  b   x  y
0  1  2   3 -1
1  2  4   6 -2
2  3  6   9 -3
3  4  8  12 -4

How can I move columns b and x such that they are the last 2 columns in the dataframe? I would like to specify b and x by name, but not the other columns.

Answer 1

You can also do this as a one-liner:

df.drop(columns=['b', 'x']).assign(b=df['b'], x=df['x'])
