Types and Data Structures

RuLA supports four fundamental types for working with data:

Type	Description	Example
String	Text values	"Hello World"
Number	Numeric values (integers and decimals)	42, 3.14
List	Ordered collections of values	['a', 'b', 'c']
Dictionary	Key-value pairs	{'name': 'John', 'age': 30}

Each type has its own syntax for creation, specific operators for manipulation, and built-in functions for common operations.

Quick Reference

Creating Values

"This is a string"      # String
42                      # Number
3.14159                 # Number
['apple', 'banana']     # List
{'x': 1, 'y': 2}        # Dictionary

Common Operations

Operation	Strings	Numbers	Lists	Dictionaries
Length	LEN	-	COUNT	COUNT
Check if empty	LEN(text) == 0	-	list == []	dict == {}
Access by index/key	text[index]	-	list[index]	dict[key]
Check containment	text contains "x"	-	contains	in
