在pandas数据帧上移动整个列

Question

I want to shift to the right an entire column, fill with NAN the first column and drop the last column:

df0:             A  B  C  D
    2013-12-31   10 6  6  5        
    2014-01-31   11 7  5  5
    2014-02-28   15 8  8  8

into

df1:             A   B  C  D
    2013-12-31   NaN 10 6  6          
    2014-01-31   NaN 11 7  5  
    2014-02-28   NaN 15 8  8  

My solution is to split the columns into Series and then recompose the dataframe. Is there a more efficient way?

Answer 1

shift shift the data by rows. Here's my trick

df.T.shift().T

Update

It's a bug when passing axis as 1. It's been solved in the current develop version. If you are living in the cutting edge, use

df.shift(axis=1)

instead.
