Python 等效于 Java 中的双冒号 (::) 运算符

Question

What is the double colon(::) operator in java also known as method reference operator in Java equivalent in python ??

Syntax:

<Class name>::<method name>

Example: "/absfds/dclckd/dsf: { "reference": false, "type": "object", "value": { "functionName": "", "artifactPath": "", "branch": "develop", "buildType": "", "buildCommand": "", "repository": "", "storageClass": "STANDARD_IA", "handler": "package along with class name::method" }, "volatile": true

The handler is inside a .json file which is accessing java files. How to write the handler when it is accessing python files. Does it remain the same ?

Answer 1

This is not a valid JSON file, at least not in this format.

To get a reference to a method in Python, you just use its name but without () , eg.

>>> import os
>>> os.getenv
<function getenv at 0x...>
>>> os.getenv('EDITOR')
'nvim'
>>> f = os.getenv
>>> f('EDITOR')
'nvim'

(ETA: it works the same way if os was a class, or an instance of a class.)
