strictTyping

Decorator to enforce the correct types for method invocation and definition.

---

The decorator will help you to validate if the input parameters have a valid type.

With enforce=True (default) it will also enforce that the function has a return type and all parameters have types defined.

Help

Works for builtins (int, floats, str, bool), classes, Union, Optional...

Currently only supports toplevel types. Not supported are nested types like "list[str]"

Only the definition of the function results type is checked, not the actual result type.

Installation

Install using pip install -U strictTyping

Examples

from strictTyping import strictTyping

# full valid function
@strictTyping()
def myFunction(argument: int) -> str:
	return str(argument)
	
myFunction(5) # succeeds
myFunction(5.0) # ValueError

# not enforcing typing
@strictTyping(enforce = False)
def myFunction(argument, argument2: float):
	return str(argument), str(argument2)
	
myFunction(5, 5.0) # succeeds
myFunction(5.0, 5) # ValueError
