Stubs with type annotations for ordered-set Python library

Last update: Feb 6, 2020

Overview

ordered-set-stubs - stubs with type annotations for ordered-set Python library

Archived - now type annotations are the part of the ordered-set library itself.

Usage

For example, you have the following code in ordered_set_stubs_test.py file:

from ordered_set import OrderedSet


# noinspection PyPep8Naming
def receives_OrderedSet_int(ordered_set: 'OrderedSet[int]') -> 'OrderedSet[int]':
    return ordered_set


receives_OrderedSet_int(OrderedSet(['ololo']))

Run mypy to check the code and check that it returns an error:

$ mypy ordered_set_stubs_test.py
ordered_set_stubs_test.py:10: error: List item 0 has incompatible type "str"; expected "int"

In Python 3.7 you can even drop quotes:

from __future__ import annotations
from ordered_set import OrderedSet


# noinspection PyPep8Naming
def receives_OrderedSet_int(ordered_set: OrderedSet[int]) -> OrderedSet[int]:
    return ordered_set


receives_OrderedSet_int(OrderedSet(['ololo']))

Cannot determine consistent method resolution order (MRO) for "OrderedSet" when used with Python 2.7
I have installed those stubs for Python 2.7 and am manipulating mypy to find them, by running mypy as follows (~/v27 is a virtualenv):

mypy test.py --python-version 2.7 --python-executable~/v27/bin/python

This give me the error

/Users/guido/v27/lib/python2.7/site-packages/ordered_set-stubs/__init__.pyi:10: error: Cannot determine consistent method resolution order (MRO) for "OrderedSet"

When used with Python 3 all is well.

Consider using pytest-mypy-plugins
Hi! Thanks for this awesome project!

I am TypedDjango team member, we maintain types for, well, django. And we do pretty much the same job.

For example, we also test our types the similar way as you do in tests/. We even created a tool called pytest-mypy-plugins (announcing post) to help us with this task. Maybe it will be also helpful to you as well.

That's how the simplest test looks like:

- case: compose_two_wrong_functions main: | from returns.functions import compose def first(num: int) -> float: return float(num) def second(num: float) -> str: return str(num) reveal_type(compose(first, second)(1)) # N: builtins.str*

Ask any questions you have!
