I want to create a python library and part of the function of this library involves creating a class instance with some user defined variables. How do I let the user write their own conditionals for the class instance in said instance's method? For example, say I have an instance of the following class:
class Test:
def __init__(self, some_value):
self.some_value = some_value
def func(self):
pass
instance = Test(4)
How do I let a user change what instance.func()
does (how can I let a user access the object's variables?
CodePudding user response:
You could pass a reference to the user's function to init For example:
class Test:
def __init__(self, user_function):
self._function = user_function
def func(self):
return self._function()
def ufunc_1():
return 'Hello world!'
def ufunc_2():
return 'Goodbye cruel world'
t_1 = Test(ufunc_1)
t_2 = Test(ufunc_2)
print(t_1.func())
print(t_2.func())
In this way, the reference to the user function is stored in an instance variable.
Output:
Hello world!
Goodbye cruel world
