Question

I have a program that runs on two platforms. Each platform has a different set of imported modules. Many of the def statements on one platform need an additional parameter to run with its set of imports. Not every def statement needs to be changed.

If something like this worked, it would be make things easier:

if platform_1:
   def func(this, that):
else:
   def func(self, this, that):

   func_body

Is there any way do do this?

Answer 1

I wonder why a function should have an argument that it never uses. Wouldn’t it be better to fix the surrounding code that forces you into this situation?

Nevertheless, it is possible…

def narcissist(func):
    def wrapper(self,*args,**kwargs):
        return func(*args,**kwargs)
    return wrapper

def identity(func):
    return func

if platform_1:
    modify_args=identity
else:
    modify_args=narcissist

@modify_args
def func(this,that):
    func_body
