So, I guess

class popenfile(NamedTuple):
    path: str
    fd: int
    if sys.platform == "linux":
        position: int
        mode: str
        flags: int

Should be:

if sys.platform == "linux":
    class popenfile(NamedTuple):
        path: str
        fd: int
        position: int
        mode: str
        flags: int
else:
    class popenfile(NamedTuple):
        path: str
        fd: int
