locale.getdefaultlocale is depreciated and will be removed in 3.15

[athompson673]

Problem Description

Use of depreciated locale.getdefaultlocale

I'm not sure how to best replace this with getlocale() as suggested by the warning message, as the output of the two is slightly different (on my machine)

IPython 8.29.0 -- An enhanced Interactive Python. Type '?' for help.

import locale

locale.getlocale()
Out[2]: ('English_United States', '1252')

locale.getdefaultlocale()

  locale.getdefaultlocale()
