I don't have a machine available right now, but I wonder what happens if two adjacent path elements are integers? Does it perform division instead of path/string concatenation?

You can't concatenate a path with an integer:

  >>> Path.cwd() / 1
  TypeError: argument should be a path or str object, not <class 'int'>

Also, note that the '/' operator is left-associative, so even if you have two adjacent numbers when joining paths, there will be no division.

  TypeError: expected str, bytes or os.PathLike object, not int

This probably means that you put a path to the left, not ints on both sides.

Well, I put a path and then two ints... if you don't start with a path it's obviously just going to be division.

The Path object won't construct a path from an integer.

    >>> from pathlib import Path
    >>> p=Path(1)
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/lib/python3.6/pathlib.py", line 979, in __new__
        self = cls._from_parts(args, init=False)
      File "/usr/lib/python3.6/pathlib.py", line 654, in _from_parts
        drv, root, parts = self._parse_args(args)
      File "/usr/lib/python3.6/pathlib.py", line 638, in _parse_args
        a = os.fspath(a)
    TypeError: expected str, bytes or os.PathLike object, not int
    >>>

So what happens if the paths are numbers? They are treated like any other characters.

p=Path(str(1))

Python is strongly typed.

Yes, that's pretty much the question metaobject was asking.

Should I have said "numeric characters" or "numeric strings" in my last paragraph instead of numbers?
