Pandas: cannot import name adjoin

问题

From Wes:

def side_by_side(*objs, **kwds):
    from pandas.core.common import adjoin
    space = kwds.get('space', 4)
    reprs = [repr(obj).split('\n') for obj in objs]
    print adjoin(space, *reprs)

Apply below:

  import pandas as pd

  df1 = pd.DataFrame(np.random.rand(10,3))
  df2 = pd.DataFrame(np.random.rand(10,3))


side_by_side(df1, df2)

Throws error:

ImportError                               Traceback (most recent call last)

      5     print adjoin(space, *reprs)

ImportError: cannot import name adjoin

回答1:

I guess this function has been moved to pandas.formats.printing:

In [69]: from pandas.formats.printing import adjoin

UPDATE: as already mentioned by @debo for Pandas 0.20.0+ use:

from pandas.io.formats.printing import adjoin

回答2:

Changed for pandas version 0.20.*

from pandas.io.formats.printing import adjoin
