This is wrong since 2770d5c (see versionchanged notes).

For example, globals can be passed as a positional argument:

>>> eval("x + 1", {'x': 1})
2

Closing since the current implementation accepts keyword-arguments.

@picnixz May I ask which version you've tested?

>>> import sys
>>> sys.version
'3.12.11 | packaged by conda-forge | (main, Jun  4 2025, 14:45:31) [GCC 13.3.0]'

>>> eval( "x + 1", globals={'x': 1})
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: eval() takes no keyword arguments

>>> exec( "x + 1", globals={'x': 1})
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'globals' is an invalid keyword argument for exec()

Python 3.13 and later. We don't update 3.12 anymore (except for security fixes).

OK, Thanks!
