ENH: DataFrame.from_xy methods are duplicates (original) (raw)

Decide what to do with each of these

• deprecate from_csv / change to be exactly like read_csv -> DEPR: Deprecate from_csv in favor of read_csv #17812
• from_dict
• from_records (see Extremely slow construction of large DataFrames out of ndarrays? #8161)
• from_items (DEPR: Deprecate from_items #18529)

This is just a suggestion: DataFrame constructor already supports the things that from_dict and from_records do (from_items is not supported by the constructor, but maybe it should be?). Also from_csv does the same thing as pd.read_csv.

Since There should be one-- and preferably only one --obvious way to do it. maybe these methods should be removed/deprecated?

I know that this would cause backward incompatibility, so maybe just a deprecation warning could be displayed until a future major release that could remove them.
