ENH: is it possible to save a reference to a method depending on the version

Thanks for opening the issue. This seems more like a usage question which should be asked on Stack overflow instead.

But, to answer your question, yes you can do that by using getattr, the implementation would look something like this:

PANDAS_VERSION = Version(pd.__version__)
PANDAS_210 = PANDAS_VERSION >= Version("2.1.0")

select_map = 'map'

if not PANDAS_210:
   select_map = 'applymap'

getattr(df, select_map)(lambda x: len(str(x)))

Another implementation would be to rely on hasattr instead of checking the pandas version, something like:

if hasattr(df, "map"):
    df.map(lambda x: len(str(x)))
else:
    df.applymap(lambda x: len(str(x)))

Feel free to choose whichever method you like!

@Aloqeely thank you. The first is what need.
