Variables:

In rickroll-lang you dont need to specify the variables type.

To create a variable you use the give and up keywords

give is similar to let or var in other languages and up is used to asign a value to the variable (kinda like =).

Example:

Create a variable named: name with value: "Rick":

take me to ur heart
    give name up "Rick" 
    i just wanna tell u how im feeling "Hello", name + "\n"
say goodbye

Datatypes

Rickroll-Lang supports many datatypes.

You can define strings, tuples, lists, integers, floats, sets and booleans

Example:

take me to ur heart
    give name up "Sid" # string
    give age up 15 # int
    give grades up 69.42 # float
    give is_cool up True # bool
    give my_tuple up ("never", "gonna", "give") # tuple
    give my_dict up ("never":"gonna", "give":"you") # dict
    give my_list up ["you", "up"] # list
    give my_set up {"never", "gonna", "let", "you", "down"} # set
say goodbye

And since this is converted to python code we know that the variables are objects and we can see their type using the var.__class_

So if we add this to the end of our file:
i just wanna tell u how im feeling variable_name.__class__
for each variable and run it, we get this

<class 'str'><class 'int'><class 'float'><class 'bool'><class 'tuple'><class 'dict'><class 'list'><class 'set'>

Lists and Tuples

To make a list in rickroll lang we use square brackets: []

Example:

give my_list up []

Lists have many functions built in such as list.append and list.remove.

We can also get the length of the list by using the built in function: length()
Usage: length(list)

To get indexes of a list we do list[index]. The index MUST be an integer. Remember indexes start from 0 not 1.

Tuples are just the same as list but they have an immutible state which means that the values in it can't be changed.

Dicts

To make a dictionary in rickroll-lang we use curly braces: {}

To add to a dict you do py: dict["key"] = "item" you can even remove from a dict using py: dict.remove()

We can also get the length of the dict by using the built in function: length()

Sets

Sets in ricklang also use curly braces: {}
Sets have built in functions too like py: set.add() and py: set.remove()

We can also get the length of the set by using the built in function: length()
