About The Project

Python 3.x provides customized callable types.

How can we distinguish between types like class, function, and method? You might think of using the types or inspect modules as a solution. However, these traditional types can be a bit confusing. Especially when it comes to distinguishing between function and method types, you'll notice that types.FunctionType does not cover types.MethodType. For this reason, callable types have been redefined using this library.

Prerequisites

Does not require any prerequisites

Installation

1. Clone the repo

git clone https://github.com/TahsinCr/python-callabletype.git

2. Install PIP packages

pip install callabletype

Usage

We have a class named Parrot(name, color, age) that includes a method walk(self). Additionally, there is a function called parrot_fly(). We can choose and control the types of these functions in detail.

from callabletype import (
    get_callable_type, is_function, CLASS, FUNCTION, METHOD, SELFMETHOD, INSTANCESELFMETHOD
)

class Parrot:
    def __init__(self, name:str, color:str, age:int):
        self.name = name
        self.color = color
        self.age = age
    
    def walk(self):
        print("The parrot named {} walked".format(self.name))
    
def parrot_fly(parrot:Parrot):
    print("The parrot named {} flew".format(parrot.name))

parrot = Parrot(name='Kiwi', color='green', age=14)

objects = {
    'function' : parrot_fly,
    'class' : Parrot,
    'method' : Parrot.walk,
    'self-method' : Parrot.walk,
    'instance-self-method' : parrot.walk
}

for type_name, object in objects.items():
    type = get_callable_type(object)
    check_function = is_function(object)
    check_method = type in METHOD
    check_class = CLASS.check_func(object)
    print("'{}' : {} (result_type={}, is_function={}, is_method={}, is_class={})\n".format(
        object, type_name, type, check_function, check_method, check_class
    ))

Output

'<function parrot_fly at 0x000001D8C23F3EC0>' : function (result_type=FUNCTION, is_function=True, is_method=False, is_class=False)

'<class '__main__.Parrot'>' : class (result_type=CLASS, is_function=False, is_method=False, is_class=True)

'<function Parrot.walk at 0x000001D8C25B1260>' : method (result_type=SELFMETHOD, is_function=True, is_method=True, is_class=False)

'<function Parrot.walk at 0x000001D8C25B1260>' : self-method (result_type=SELFMETHOD, is_function=True, is_method=True, is_class=False)

'<bound method Parrot.walk of <__main__.Parrot object at 0x000001D8C2455BE0>>' : instance-self-method (result_type=INSTANCESELFMETHOD, is_function=True, is_method=True, is_class=False)
