pyarray

pyarray

A node module for manipulating arrays just like how you would in Python!

Install

Features

• Supports all native javascript array methods, such as push, indexOf etc.
• Supports native Python list methods too!
• Not only that, but you can also use index ranges and negative indexes, no more array[array.length-1]

Methods

For detailed information about pyarray's method behaviour visit Python's official docs. Even the errors are the same!

Python method	Supported?	Note
list.append(x)	Yes	Identical to Array.prototype.push
list.extend(L)	Yes
list.insert(i, x)	Yes
list.remove(x)	Yes
list.pop([i])	Yes	Renamed to pypop to avoid conflict with Array.prototype.pop
list.index(x)	Yes
list.count(x)	Yes
list.reverse()	Yes	Identical to Array.prototype.reverse
list.sort()	No

Examples

import pyarray from 'pyarray'

Creating a pyarray

let fruits = pyarray(['Banana', 'Apple', 'Orange', 'Plum', 'Grape'])

Accessing elements

Python	pyarray	Result
fruits	fruits.get()	['Banana', 'Apple', 'Orange', 'Plum', 'Grape']
fruits[0]	fruits[0]	'Banana'
fruits[-1]	fruits[-1]	'Grape'
fruits[0:-2]	fruits['0:-2']	['Banana', 'Apple', 'Orange']
fruits[0:-1:2]	fruits['0:-1:2']	['Banana', 'Orange']
fruits[::-1]	fruits['::-1']	['Grape', 'Plum', 'Orange', 'Apple', 'Banana']
You can also use the .get() method as a fallback, the syntax is
obj.get(start, end, step)
