JavaScript object 文字与 Python 字典是否相同？

Question

I've started using JavaScript recently and have noticed a resemblance between JavaScript object literals and python dictionaries. They are used in similar situations and have similar syntax. So are they basically the same thing but with different names?

Answer 1

They have the same structures; key: value . The key could be an array, integer, object etc. Same goes for the value.

Python:

my_python_dictionary = {'name': 'John', age: 5, 123: 'a string'}
one_of_the_values_of_my_python_dictionary = my_python_dictionary['name']

JavaScript:

let myJavaScriptObjectLiteral = {"name": "John", age: 5, 123: "a string"}
let oneOfTheValuesOfMyJavaScriptObjectLiteral = myJavaScriptObjectLiteral["name"]

Answer 2

it is totally not the same thing. in JS, object literals is a object, so you can combine them with data and function, and you can call the method by dot, just like x.xxx(), and you can deconstruction it with the same symbol {...}, just like other object.

but in python, dict is not a object, you can not use dot, and if you want deconstruction, you must use ** for it, by the way, you can deconstruction turple by *

summarize: their is nothing just like object literals in python...
