asjs

Python module for implement object with syntax from JavaScript. Implementing access to keys by obj.path.to.your.key notation as in JavaScript

Installing

pip install asjs

or like this:

curl https://github.com/tankalxat34/pyasjs/raw/main/asjs.py -o asjs.py

Using

Recommended import statement:

from asjs import ObjectNotation

Creating new object

Using dictionary:

obj = ObjectNotation({"key1": "value1", "key2": "value2", "key3": {"a": "b", "lst": [14, 5, 6, 12]}})

Using arguments:

obj = ObjectNotation(key1="value1", key2="value2", key3={"a": "b", "lst": [14, 5, 6, 12]})

Getting values by keys or indexes

>>> obj[0]
value1
>>> obj.key2
value2
>>> obj["key3"]
[14, 5, 6, 12]

Creating new keys in object

obj.year = 2023

or:

>>> year = 2023
>>> obj.set(year)

or:

>>> obj["year"] = 2023

Saving functions in object

>>> obj.fibonachi = lambda n: 1 if n <= 2 else obj.fibonachi(n - 1) + obj.fibonachi(n - 2)

>>> obj.fibonachi(7)
13

Removing keys by string-names or indexes

>>> del obj.year

or:

>>> del obj[-1]

or:

>>> del obj["year"]

Changing value by key

>>> obj.key1 = 123

or:

>>> obj["key1"] = 123

Cycle for by object

Indexes:

>>> for i in range(len(obj)):
...     print(i)
0
1
2

Keys:

>>> for k in obj:
...     print(k)
key1
key2
key3
fibonachi

Values:

>>> for v in obj.values():
...     print(v)
123
value2
JSObject(a: 'b', lst: JSObject(0: 14, 1: 5, 2: 6, 3: 12))
<function <lambda> at 0x0000020189F19480>

Boolean statements

>>> "key3" in obj
True
>>> "fake_key" in obj
False

isArray function

>>> obj.isArray()
False
>>> obj.key3.lst.isArray()
True

toList function

>>> obj.toList()
Traceback (most recent call last):
  ...
TypeError: Object is not be able to convert to list
>>> obj.key3.lst.toList()
[14, 5, 6, 12]

Slices

>>> obj[0:3]
('value1', 'value2', <asjs.ObjectNotation object at 0x000001D7195A1990>)
>>> obj.key3.lst[0:3]
(14, 5, 6)
