Typing is the concept or system that assigns types to values and expressions in a program.

  • It is the overall system or bigger idea of describing types in code (int, string, etc.)
  • It is a property or part of a programming language
  • It will exist in a programming language, whether you check for it or not
  • It is different from Type Checking (which is a process or tool that validates assigned types to values)

Typing = the data (the type label on values)

Typing in Python

The actual syntax or annotations we write in Python to express typing is called Type Hints.
