Assigning Variables

Variables are assigned with a key and a value. Key names must be valid identifiers, meaning they must contain no spaces or symbols except underscore (_). Values can be assigned to variables with or without an equals sign (=):

my_favorite_number = 42
my_favorite_color "Magenta"
is_but_a_flesh_wound yes

When left without a value, variables will evaluate to null/None:

set_to_null =
also_null
but_this_has_a_value 15

Data Types

• Numbers

  Numbers can be positive integers or floats:

  1 1.2 1_000 0.123 .123_4

• Booleans

  The boolean values True and False are given using these variants:

  True true yes
  False false no

• Strings

  Single-line strings can be enclosed by single quotes ('), double quotes (") or backticks (`), and multiline strings are enclosed by three of any of those:

  foo "abc"
  bar 'def'
  baz '''Hi,
          did you know
              you're cute?
                  '''

• Lists

  Lists are enclosed by square brackets ([]). Elements inside lists are separated by spaces, commas or line breaks:

  groceries [
      "bread",
      "milk" "eggs"
      "spam"
  ]

• Mappings

  Mappings are groups of key-value pairs enclosed by curly braces ({}). Values may be any expression, even other mappings:

  me {
      name "Samantha"
      age 24
      job "Developer"
      favorite_things {
          editor "Vim"
          languages ["Python", "Rust"]
      }
  }

  Mappings may also take the form of dotted attribute lookups:

  outer.middle.inner yes  # == {'outer': {'middle': {'inner': True}}}

• Comments

  Single-line comments are made using the # symbol:

  option = "The parser reads this."
  # But this is a comment.
      #And so is this.
  option2 = "# But not this; It's inside a string."
  # The parser ignores everything between ``#`` and the end of the line.
   #   ignore = "Comment out any lines of code you want to skip."
