Variables

Variables are named storage slots for objects. They are dynamically typed, meaning a variable can hold any type of object.

Variable Rules

Naming:

• Must start with a letter (a-z, A-Z) or _.
• Subsequent characters can be letters, digits (0-9), ', or ~.
• Case-sensitive: x ≠ X.
• Reserved keywords cannot be used as variable names (e.g., if, else, function, while, True, False, None).

Assignment:

• Use = to assign a value.
• If the variable doesn’t exist, it is created automatically.
• Assignment returns None.

Examples

# Basic assignment
x = 10
name = "Neon"

# Multiple assignments (chained)
100 -> a -> b -> c  # a, b, c all = 100

# Swapping variables
a = 5
b = 10
a <-> b  # Now a = 10, b = 5

# Deleting a variable
x = 42
del x    # x no longer exists
