How to select all columns, except one column in pandas?

I have a dataframe look like this:

    import pandas
    import numpy as np
    df = DataFrame(np.random.rand(4,4), columns = list('abcd'))
    df
          a         b         c         d
    0  0.418762  0.042369  0.869203  0.972314
    1  0.991058  0.510228  0.594784  0.534366
    2  0.407472  0.259811  0.396664  0.894202
    3  0.726168  0.139531  0.324932  0.906575

How I can get all columns except column b?

When you don't have a MultiIndex, df.columns is just an array of column names so you can do:

    df.loc[:, df.columns != 'b']

              a         c         d
    0  0.561196  0.013768  0.772827
    1  0.882641  0.615396  0.075381
    2  0.368824  0.651378  0.397203
    3  0.788730  0.568099  0.869127
