DEPR: let's deprecate (original) (raw)

xref #18202

We have some cruft, let's deprecate it (I have noted some which already have an issue associated).

From ndarray

• Series.compress() (DEPR: Series.compress #21930)
• Series.imag / Series.real (DEPR: Series.put, Series.real, Series.imag, Index.dtype_str #27106)
• Series.nonzero() (Deprecate series.nonzero (GH18262) #24048)
• Series.put() (DEPR: Series.put, Series.real, Series.imag, Index.dtype_str #27106)
• Series.itemsize
• Series.flags
• Series.strides

timeseries specific

• Series.first()
  let head / tail take a timedelta
• Series.last()

other

• Series.swapaxes()
  • No reason once panel is gone.

non-controversial

• MultiIndex.to_hierarchical (only used for Panel) (DEPR: MultiIndex.to_hierarchical #21613)
• Series/DataFrame.compound() (DEPR: deprecate Series/DataFrame.compound #26405)
• Series.ptp() (DEPR: Series.ptp() #21614)
• Series.from_array (Deprecate Series.from_array ? #18213)
• Series.valid() (DEPR: Deprecate Series.valid #18800)
• Series/DataFrame.slice_shift() (DEPR: DataFrame/Series.slice_shift #37601)
• Series/DataFrame.tshift() (DEPR: Deprecate tshift and integrate it to shift #34545)
• Series/DataFrame.get_values() (DEPR: .get_values() #19617)
• Index.dtype_str (DEPR: Series.put, Series.real, Series.imag, Index.dtype_str #27106)
• Index.summary() (Deprecate Index.summary #18217)
• .get_ftype_counts (DEPR: deprecate get_ftype_counts #18243) (DEPR: deprecate get_ftype_counts (GH18243) #20404)
• .get_dtype_counts DEPR: DataFrame.get_dtype_counts #27145
• Index/Series.asobject (Deprecate Series.asobject, Index.asobject, rename to _asobject #18237) (DEPR: deprecate .asobject property #18572)
• Index.to_native_types() (make private) (DEPR: Index.to_native_types #36418)
• DataFrame/Series.as_matrix (DEPR: Deprecate NDFrame.as_matrix #18458)
• .clip_upper/.clip_lower (replace by .clip) (DEPR: Deprecating .clip_lower and .clip_upper #24203)

Potentially

• .ftypes (DEPR: deprecate get_ftype_counts #18243) (Deprecated Series.ftype, Series.ftypes and DataFrame.ftypes features #26744)
• .xs() (CLN: implement xs in terms of loc #6249)
• .iat/.at
• .take
• .lookup (DEPR: DataFrame.lookup #35224)
• DataFrame.from_items
• Series/DataFrame.add_prefix/add_suffix (DEPR: deprecate .add_prefix and .add_suffix #18347)
  • Maybe add suffix / prefix to concat?
• NDFrame.filter
