def iter_rows(self, *entries):
"""Iterate over the columns in a wordlist.
Parameters
----------
entries : list
The name of the columns which shall be iterated.
Returns
-------
iterator : iterator
An iterator yielding lists in which the first entry is the ID of
the wordlist row and the following entries are the content of the
columns as specified.
Examples
--------
Load a wordlist from LingPy's test data::
>>> from lingpy.tests.util import test_data
>>> from lingpy import Wordlist
>>> wl = Wordlist(test_data("KSL.qlc"))
>>> list(wl.iter_rows('ipa'))[:10]
[[1, 'ɟiθ'],
[2, 'ɔl'],
[3, 'tut'],
[4, 'al'],
[5, 'apa.u'],
[6, 'ʔayɬʦo'],
[7, 'bytyn'],
[8, 'e'],
[9, 'and'],
[10, 'e']]
So as you can see, the function returns the key of the wordlist as well
as the specified entry.
