Given a character array:

In [21]: x = np.array(['a     ','bb   ','cccc    '])

One can remove the whitespace using:

In [22]: np.char.strip(x)
Out[22]: 
array(['a', 'bb', 'cccc'], 
      dtype='|S8')

but is there a way to also shrink the width of the column to the minimum required size, in the above case |S4?
