typing

I closely paralleled the approach taken in how-to-use-moment-js-library-in-angular-2-typescript-app but still get error TS2307: Cannot find module 'mqtt'. npm install --save mqtt <s>typings install --save mqtt</s that didn't find the typings but this did... typings install mqtt --save --ambient my tsconfig.conf looks like this { "compilerOptions": { "noImplicitAny": true, "module": "commonjs", "target": "ES5", "emitDecoratorMetadata": true, "experimentalDecorators": true, "sourceMap": true, "declaration": true }, "files": [ "ng2-mqtt.ts" ], "exclude": [ "node_modules" ] } and ng2-mqtt.ts just

I am trying to write code which uses the Coroutine class, as described in the typing documentation . It's look like it's available in python 3.5 , but when I am typing to import it throws me an ImportError : In [1]: from typing import Coroutine ImportError: cannot import name 'Coroutine' Then, I tried to run the code in Python 3.6 and it worked fine. Does this class not available in python 3.5 ? If not, why it's appear in the documentation (of python 3.5 in particular)? I tried to run it with python 3.5.2 . The library typing was not official on 3.5, but became official on 3.6. So for older

I have this piece of code: import enum class Color(enum.Enum): RED = '1' BLUE = '2' GREEN = '3' def get_color_return_something(some_color): pass How do I properly add type annotations to the some_color varaible in this function, if I suppose to receive a value from the Color enum (for example: Color.RED )? Type hinting the Color class should work: def get_color_return_something(some_color: Color): print(some_color.value) def get_color_return_something(some_color: Color): pass 来源： https://stackoverflow.com/questions/52624736/python-type-annotations-for-enum-value

This question already has answers here : Type hint for a function that returns only a specific set of values (3 answers) I'm using the new Python 3.5 module typing and it has been joyous. I was wondering how one might specify a type based on an exact string literal. For example, a function is guaranteed to return one of the four strings - "North", "West", "East", "South - how can we express that as a specific type variable, instead of just str . I looked through the documentation, finding the Union type and the TypeVar function, but was unable to find an answer. An example function expressing

Laracasts set this using define, IIRC. Is there a way to have strict type hinting on scalars in one file (like a math library) while at the same time using non-strict elsewhere WITHOUT just arbitrarily changing settings in your code? I'd like to avoid introducing bugs by not fidgeting with the language settings, but I like this idea. 回答1: Indeed, you can mix and match to your heart's content, in fact
