Description
The page http://pandas.pydata.org/pandas-docs/dev/generated/pandas.Series.html says:
index : array-like or Index (1d)
Values must be unique and hashable, same length as data.
A little bit earlier the same page says:
Labels need not be unique but must be any hashable type.
Other pages also mention non-unique index support (e.g. http://pandas.pydata.org/pandas-docs/dev/dsintro.html) It looks like index description should read:
index : array-like or Index (1d)
Values must be hashable, same length as data. Non-unique index values are allowed.
