python - How do I convert a MultiIndex to type string -

consider multiindex idx idx = pd.multiindex.from_product([range(2013, 2016), range(1, 5)]) when do idx.to_series().str.join(' ') i get 2013 1 nan 2 nan 3 nan 4 nan 2014 1 nan 2 nan 3 nan 4 nan 2015 1 nan 2 nan 3 nan 4 nan dtype: float64 this happens because dtypes of different levels int , not str . join expects str . how convert whole idx str ? i've done join = lambda x, delim=' ': delim.join([str(y) y in x]) idx.to_series().apply(join, delim=' ') 2013 1 2013 1 2 2013 2 3 2013 3 4 2013 4 2014 1 2014 1 2 2014 2 3 2014 3 4 2014 4 2015 1 2015 1 2 2015 2 3 2015 3 4 2015 4 dtype: object i expect there simpler way i'm overlooking. i'm not sure it's elegant way, should work: idx.get_level_values(0).astype(str).values + ' ' + idx.get_le...
