Arrays

arrays are a list from variables.

look at this example:

$names = ['parsa', 'pashmak', 'jack']

println($names) # output: ['parsa', 'pashmak', 'jack']
println($names[0]) # output: parsa
println($names[1]) # output: pashmak
println($names[2]) # output: jack

this is a example about array and loop:

$names = ['parsa', 'pashmak', 'jack']

$i = 0

while $i < len($names)
    println($names[$i])
    $i = $i + 1
endwhile

output:

parsa
pashmak
jack

the above code prints names one by one

adding new item to array

you can add new item to an array by using python append and insert methods:

$myarray = ['first', 'second']
println($myarray)

$myarray->append('new item')
println($myarray)

output:

['first', 'second']
['first', 'second', 'new item']

also with insert method you can set the location of new item:

$myarray = ['one', 'two', 'four']
println($myarray)

$myarray->insert(2, 'three')
println($myarray)

output:

['one', 'two', 'four']
['one', 'two', 'three', 'four']

removing an item from array

you can delete an item from array by using python pop method:

$myarray = ['first', 'second']
println($myarray)

$myarray->pop(1)
println($myarray)

output:

['first', 'second']
['first']

also pop method without argument removes last item by default.

setting value of an item in array

look at this example:

$abc = ['a', 'b', 'c']
println($abc) # output: ['a', 'b', 'c']

$abc[0] = '000'
println($abc) # output: ['000', 'b', 'c']

like above example, we can set a specify item of array with a syntax like this: $my_list[<index>] = <value>.

also you can do this on a subitem. look at this example:

$my_list = []
$my_list->append(['a'])

println($my_list[0]) # output: ['a']

$my_list[0][0] = 'AAA'

println($my_list[0]) # output: ['AAA']

Dictonaries

dictonaries are like lists, but in dicts you can set a string as key instead of index number.

look at this example:

$my_dict = {'hello': "Hello world", 'bye': 'Good bye!'}

println($my_dict) # output: {'hello': "Hello world", 'bye': 'Good bye!'}

println($my_dict['hello']) # output: Hello world

like above example, we can use string as key instead of index number. in the above example, hello is the key.

also you can set the keys like lists(arrays):

$my_dict = {'hello': "Hello world", 'bye': 'Good bye!'}
println($my_dict['hello']) # output: Hello world

$my_dict['hello'] = 'new hello'

println($my_dict['hello']) # output: new hello

The list(Array) and dict are python datatypes(means you can use all of python list and dict methods on them).
