What differs from mypy stubgen?
As mypy's stubgen -m random generates the following for the random module:
class Random(_random.Random):
VERSION: int = ...
gauss_next: Any = ...
def __init__(self, x: Optional[Any] = ...) -> None: ...
def seed(self, a: Optional[Any] = ..., version: int = ...) -> None: ...
def getstate(self): ...
def setstate(self, state: Any) -> None: ...
def __reduce__(self): ...
def randrange(self, start: Any, stop: Optional[Any] = ..., step: int = ..., _int: Any = ...): ...
def randint(self, a: Any, b: Any): ...
def choice(self, seq: Any): ...
...pystubber random instead generates:
#!/usr/bin/env python # [module random]
"""
Random variable generators.
