I’m using python3.8 and multipledispatch library in order to overload a method signature. multipledispatch documentation examples suggests overloading like this: from multipledispatch import dispatch @dispatch(int, int) def add(x, y): print(x + y) @dispatch(str, str) def add(x, y): print(f'{x} {y}’) add(1, 2) add(‘hello’, ‘world’) but in my case I want to call add with keyword arguments ..

I have two classes A and B(A). Their constructor accept the style dictionary as a keyword argument. For A objects I want, by default, the string green to be associated to style[‘color’]. For B objects color defaults to red. I came up with this solution but find it rather clumsy. Is there a more elegant ..
I have a function answer_question: NOTICE: 2 normal arguments in this function. def answer_question(question, answer_type, **kwargs): # do xyz return answer I have another function that uses it that I want to process a dictionary of questions. That dict would look like this: # Format: question: answer_settings questions_dict = { ‘What’s your favorite color?’: {‘answer_type’: ..
For some context, I am coding some geometric transformations into a python class, adding some matrix multiplication methods. There can be many 3D objects inside of a 3D "scene". In order to allow users to switch between applying transformations to the entire scene or to one object in the scene, I’m computing the geometric center ..
I have a problem with the dictionary I don’t know how to convert args to kwargs I tried to find way to solve this problem on the internet but I don’t understand Can someone explain it for me? Ex: "I": 1 => 1:"I" convert = {‘I’: 1, ‘V’: 5, ‘X’: 10, ‘L’: 50, ‘C’: 100, ..
What is the right way to build wrappers around the test_train_split function with *args and **kwargs? To give more context, data science often require to create a test-validate-train split, so I thought to build a wrapper like def train_validate_test_split(*dataframe, **options): train, test = train_test_split(dataframe, options) train, val = train_test_split(train, options) return train, val, test that ..
I’m studying someone else’s solution on Codewars and am a little puzzled about something. Here is a link to the original question: Reverse or Rotate?. Credit goes to the original author, falsetru. Here’s the solution: def revrot(strng, sz): return ”.join( chunk[1:] + chunk[:1] if sum(int(d)**3 for d in chunk) % 2 else chunk[::-1] for chunk ..
So I’m a beginner in Python and I have this task. So, I have a tuple of random numbers, my job is to make a function that I can use to multiply these tuple of numbers, my mentor recommends me to use args (*args). ~ThankYou~ Source: Python..
I wanted to have a small function that prints an error message and then terminates the program. When I changed the program termination method from sys.exit() to raise RuntimeError(), suddenly my message stopped being printed. I then debugged the method for some time, but I do not understand why the order of the prints is ..
Is it possible to iterate args and kwargs at one time? Something like def func(*args, **kwargs): for i, t in args, kwargs: print(i, t) Source: Python-3x..
