Strong vs strict typing
WebThis has nothing to do with dynamic versus static typing, which is about WHEN to check for types. Strong versus weak is about HOW SERIOUS DO YOU GET while checking the types. You can say that weak typing is relaxed typing, and strong typing is strict typing. Unlike dynamic vs static, the strength of the typing system is a spectrum. Generally, a strongly typed language has stricter typing rules at compile time, which implies that errors and exceptions are more likely to happen during compilation. Most of these rules affect variable assignment, function return values, procedure arguments and function calling.

For some languages, the programmer must specify what type each variable is (e.g C, C++, Java), other languages offer some form of type inference (e.g. Scala, Haskell).

Instead you check for the presence of a given method or attribute. As an example, you can call len () on any Python object that defines a .__len__ () method: >>>
