• Language Server version: 2020.9.5
• OS and version: Windows 10
• Python version (& distribution if applicable, e.g. Anaconda): Anaconda Python 3.7.5

Expected behaviour

No error

Actual behaviour

import pandas as pd

ri = pd.RangeIndex(4)
print(ri)

reports

Argument of type "Literal[4]" cannot be assigned to parameter "data" of type "Iterable[Unknown]" in function "__init__"
  "__iter__" is not present

Possible fix:

diff core/indexes/range.pyi.ORIG core/indexes/range.pyi
6c6,7
<     def __new__(cls, start = ..., stop = ..., step = ..., dtype = ..., copy: bool = ..., name = ...): ...
---
>     def __new__(cls, start: Union[int, RangeIndex] = ..., stop: int = ..., step: int = ..., dtype = ..., copy: bool = ..., name = ...): ...
>     def __init__(self, start: Union[int, RangeIndex] = ..., stop: int = ..., step: int = ..., dtype = ..., copy: bool = ..., name = ...): ...
