ERR: disallow RangeIndex() · Issue #13793 · pandas-dev/pandas (original) (raw)
xref #13749
this is not consistent with other Indexes where we don't allow them to be constructed with no data passed (it can be None
), but that's the idea. start
must be not-None.
IOW this should raise ValueError
In [3]: pd.RangeIndex()
Out[3]: RangeIndex(start=0, stop=0, step=1)
