Copying MultiIndex dataframes with pd.read_clipboard?

Question

Given a dataframe like this:

          C
A   B      
1.1 111  20
    222  31
3.3 222  24
    333  65
5.5 333  22
6.6 777  74 

How do I read

Answer 1

UPDATE: now it parses the clipboard - i.e. no need to save it beforehand

def read_clipboard_mi(index_names_row=None, **kwargs):
    encoding = kwargs.pop('encoding', 'utf-8')

    # only utf-8 is valid for passed value because that's what clipboard
    # supports
    if encoding is not None and encoding.lower().replace('-', '') != 'utf8':
        raise NotImplementedError(
            'reading from clipboard only supports utf-8 encoding')

    from pandas import compat, read_fwf
    from pandas.io.clipboard import clipboard_get
    from pandas.io.common import StringIO
    data = clipboard_get()

    # try to decode (if needed on PY3)
    # Strange. linux py33 doesn't complain, win py33 does
    if compat.PY3:
        try:
            text = compat.bytes_to_str(
                text, encoding=(kwargs.get('encoding') or
                                get_option('display.encoding'))
            )
        except:
            pass

    index_names = None
    if index_names_row:
        if isinstance(index_names_row, int):
            index_names = data.splitlines()[index_names_row].split()
            skiprows = [index_names_row]
            kwargs.update({'skiprows': skiprows})
        else:
            raise Exception('[index_names_row] must be of [int] data type')

    df = read_fwf(StringIO(data), **kwargs)
    unnamed_cols = df.columns[df.columns.str.contains(r'Unnamed:')].tolist()

    if index_names:
        idx_cols = df.columns[range(len(index_names))].tolist()
    elif unnamed_cols:
        idx_cols = df.columns[range(len(unnamed_cols))].tolist()
        index_names = [None] * len(idx_cols)

    df[idx_cols] = df[idx_cols].ffill()
    df = df.set_index(idx_cols).rename_axis(index_names)

    return df

testing multi-index DF without index names:

In [231]: read_clipboard_mi()
Out[231]:
          C
1.1 111  20
    222  31
3.3 222  24
    333  65
5.5 333  22
6.6 777  74

testing multi-index DF with index names:

In [232]: read_clipboard_mi(index_names_row=1)
Out[232]:
          C
A   B
1.1 111  20
    222  31
3.3 222  24
    333  65
5.5 333  22
6.6 777  74

NOTE:

1. it's not well tested
2. it does NOT support multi-level columns
3. see point 1 ;-)
