Summary

This PR fixes a grammatical issue in the TypeError message raised when a ufunc (such as np.hypot) receives an incorrect number of positional arguments.

Previously, the message always used:

hypot() takes from 2 to 3 positional arguments but 1 were given

This PR ensures that when exactly one argument is passed, the message reads:

hypot() takes from 2 to 3 positional arguments but 1 was given

Changes

• Updated error message formatting logic in:
  • npy_argparse.c
  • ufunc_object.c
• Added regression tests under test_umath.py to assert correct grammar for singular and plural argument count cases.

Related Issue

Closes #29259

Additional Notes

• Follows TDD approach: test first, then fix.
• Verified via pytest numpy/_core/tests/test_umath.py -k TestHypotErrorMessages
• Thanks to maintainers for pointing to the relevant code sections.
