How to rearrange Pandas column sequence?

Question

>>> df =DataFrame({\'a\':[1,2,3,4],\'b\':[2,4,6,8]})
>>> df[\'x\']=df.a + df.b
>>> df[\'y\']=df.a - df.b
>>> df
   a  b   x  y
0          


        

Answer 1

You could also do something like this:

df = df[['x', 'y', 'a', 'b']]

You can get the list of columns with:

cols = list(df.columns.values)

The output will produce something like this:

['a', 'b', 'x', 'y']

...which is then easy to rearrange manually before dropping it into the first function
