true:
In [25]: a
Out[25]:
array(['abc', 'def', 'abc', 'ghij'],
dtype='|S4')
In [27]: np.equal(a,a)
Out[27]: NotImplemented
however:
In [28]: a == a
Out[28]: array([ True,

but we can make it a numpy question!
In [15]: a = np.array(['abc','def','abc','ghij'])

That's a Python question, not a NumPy question.
So comp.lang.python would be a better forum.
But here's a simplest solution::
a = ['abc','def','abc','ghij']
for it
Hi all,
how can I obtain the multiplicity of an entry in a list
a = ['abc','def','abc','ghij']
The multiplicity of 'abc' is 2.
'def' is 1.
'ghij' is 1.
