BUG? Reshaping a Series

[szli]

It looks to me like a bug in pandas.Series.

a = pd.Series([1,2,3,4])
b = a.reshape(2,2)
b

b has type Series but can not be displayed, the last statement gives exception, very lengthy, the last line is "TypeError: %d format: a number is required, not numpy.ndarray". b.shape returns (2,2), which contradicts its type Series. I am guessing perhaps pandas.Series does not implement reshape function and I am calling the version from np.array. I am at pandas 0.9.1. Some discussion on stackoverflow is here http://stackoverflow.com/questions/14390224/reshape-of-pandas-series

If it does not make sense to reshape a Series, should it throw an exception?

Fixed in #3127

You are specifing invalid input here, I think you want (2,2) as input where you will get back an ndarray
(as a 2-d reshape is not allowed)

In [2]: a = pd.Series([1,2,3,4])

In [4]: a.reshape((2,2))
Out[4]: 
array([[1, 2],
       [3, 4]])

In [5]: a.reshape(2,2)
---------------------------------------------------------------------------
TypeError: must specify a tuple / singular length to reshape

@y-p seems reasonable?

very much so.
