 It also works for Series.
 
 ```python
-In [10]: dta.A.select == 'A'
+In [10]: dta.X.select == 'A'
 Out[10]:

 3     A
 6     A
 9     A
 12    A
-Name: A, dtype: object
+Name: X, dtype: object
 ```
 
 Though the string and datetime accessor APIs are slightly inconsistent. They're available via the select accessor now.
 
 ```python
-In [11]: dta.A.select.str.contains('B')
+In [11]: dta.X.select.str.contains('B')
 Out[11]:
 1     B
