[New-bugs-announce] [issue24549] string.format() should have a safe_substitute equivalent, to be run consecutively

[azrdev]

New submission from azrdev:

"{1} {0}".format('one').format('two')

should return "two one", but throws

    IndexError: tuple index out of range


This would allow partial replacements, similar to string.Template.safe_substitute()
I suggest an analog construction (e.g. a method string.safe_format() )
