localcontext
- localcontext(ctx=None, **kwargs)
Return a context manager for a copy of the supplied context. That will set the default context to a copy of ctx on entry to the with-statement and restore the previous default context when exiting the with-statement. If no context is specified, a copy of the current default context is used.

>>> format(Decimal('2.675'), "f") '2.675' >>> format(Decimal('2.675'), ".2f") '2.68' >>> f"{Decimal('2.675'):.2f}" '2.68' >>> format(Decimal('2.675'), ".2e") '2.68e+0' >>> with localcontext() as ctx: ... ctx.rounding = ROUND_DOWN ... print(format(Decimal('2.675'), ".2f")) ... 2.67
