Description

Describe the bug
The tuples argument type of core.indexes.multi.MultiIndex.from_tuples might be Iterables, not Sequence.

Comparison of the function signature in pandas-stub:

tuples: Sequence[tuple[Hashable, ...]],

and pandas:
https://github.com/pandas-dev/pandas/blob/513e78760a8faee6723908ca23ea83dcabc5dd77/pandas/core/indexes/multi.py#L521

To Reproduce

  1. Provide a minimal runnable pandas example that is not properly checked by the stubs.
import pandas

pandas.MultiIndex.from_tuples(zip(['a'], ['b']))
  1. Indicate which type checker you are using (mypy or pyright).
    mypy

  2. Show the error message received from that type checker while checking your example.

error: Argument 1 to "from_tuples" of "MultiIndex" has incompatible type "zip[tuple[str, str]]"; expected "Sequence[tuple[Hashable, ...]]"  [arg-type]

Please complete the following information:

  • OS: MacOS
  • OS Version: Sequoia 15.3
  • python version: Python 3.10
  • version of type checker: mypy 1.15.0
  • version of installed pandas-stubs: 2.2.3.250308
