[New-bugs-announce] [issue23578] struct.pack error messages do not indicate which argument was invalid

[Alistair Lynn]

New submission from Alistair Lynn:

In this example:

  struct.pack('!hhhh', 0x5FFF, 0x6FFF, 0x7FFF, 0x8FFF)

Python errors that the 'h' format requires -32768 <= number <= 32767, but it does not indicate which of the arguments is at fault. In this contrived example it's clearly the fourth one, but in dealing with large amounts of data it would be useful to indicate which argument was invalid.

This would hopefully not be a functional change, just a slightly more helpful error message.
