处理不带参数但有时使用来自 bind 的事件调用的函数的最佳方法？

Question

I know that I can use event=None and this works fine however PyCharm likes to complain about this as the event is never used in the function. What is the best way to satisfy PyCharm's inspector. For this notice:

Take this function:

def funct(event=None):
   #  do stuff

Where I have a button command that calls it:

tk.Button(root, text='Ok', command=funct)

Or a bind that can call it:

root.bind(<Return>, funct)

Now because binds always sent an event what is the best way to tell the function to accept calls to it with or without an argument and wont trip PyCharm's inspector.

Am I missing something or is this inspector just overly cautious?

I could change the bind to use a lambda and then I can remove event=None from the function:

root.bind(<Return>, lambda e: funct)

That seams like over kill for this.

I don't think I should just throw event in the function so PyCharm stops complaining that event is not used.

I have tried also to use _ in the argument place however doing so requires some argument to be sent so I would have to perform a lambda in the button command for this to work and again feels like overkill.

So that leads me to my question.

Is there a know method of handling this that I am not aware of or do I have to just deal with the inspectors message always on my screen?

Note: I did try to remove this notice from the settings but I could not find the notice for this particular notification to remove...

Answer 1

For my needs the simple solution was to use _=None as mentioned by Iain Shelvington .

However for completeness sake I combined the use of *args, **kwargs with _ to have a catch all that PyCharm does not complain about and will catch anything that is passed to the function be it positional or named.

Example:

def test(*_args, **_kwargs):
    print('test')


test()
test('1')
test(x='1')
