Data Types

overview

Summary

Data types classify values. Remember common primitive_types: integers, floats, strings, booleans, and null_none. Common composite_types include arrays_lists and objects_dicts. A data_type defines what operations are valid and how memory is used. Languages differ: static_typing checks types at compile time; dynamic_typing checks at runtime. You can convert with type_casting. Some values use immutability. Tools may guess with type_inference. Choose the right type to store, compare, and compute correctly.
