In [1]: lst = ['A', 'B', 'C', 'D', 'E']

In [2]: import pandas.core.algorithms as algos

In [3]: algos.unique(lst)
Out[3]: array([A, B, C, D, E], dtype=object)

In [4]: len(algos.unique(lst)) # --> triggers "Python has stopped working..."

Oddly enough this actually works:

In [3]: rs = algos.unique(lst)

In [4]: len(rs)
Out[4]: 5
