Make a data profiler class that takes as params on the init a list of data
I need this class to include the following methods only using self: get_summary_stats: should calculate the mean, min and max. min_max_scale: converts the array to 0-1 values. score_scale: converts the array to zscores. I’m trying it this way without luck, when you run it it smoothly goes by but when I add the last line it gives me an error
PYTHON TypeError: validTicTacToe() missing 1 required positional argument: ‘board’
I am new to python and trying to run this code on VScode. It gives an error saying TypeError: validTicTacToe() missing 1 required positional argument: ‘board’. What am I doing wrong here?

Extending dictionary with cascading methods
I am extending the dict class in python: I would like to be able to do: the problem I have here is that jmespath can return a list, so I cannot do: Next idea would be creating a prettyprint class that superDict would inherit from and could also be used in the return of search: But I can’t figure out
In PyQT why somes widgets needs the “self” parameter before calling them, while others don’t
I’m a little bit confused about the use of the “self” parameter with some widgets like (QLineEdit), indeed when learning to use the QLabel widget, I used to call the class without the self paramater, or when using the QLineEdit widget, the widget wouldn’t work without the “self” parameter, here’s the code I’m working on : So here is where

Confusion about scoping in python classes
I am currently reviewing the python tutorials of python.org. I come from C++ and in the Classes tutorial (https://docs.python.org/3/tutorial/classes.html) I see that the scoping is similar to that in C++. It says the following about scoping and nesting: “At any time during execution, there are at least three nested scopes whose namespaces are directly accessible: – the innermost scope, which
TypeError: generatecode() takes 0 positional arguments but 1 was given
I have the code below: Then, I got the error below: TypeError: generatecode() takes 0 positional arguments but 1 was given So, how can I solve the error? Answer When you call a method on a class (such as generatecode() in this case), Python automatically passes self as the first argument to the function. So when you call self.my_func(), it’s
Python classes self.variables
I have started learning python classes some time ago, and there is something that I do not understand when it comes to usage of self.variables inside of a class. I googled, but couldn’t find the answer. I am not a programmer, just a python hobbyist. Here is an example of a simple class, with two ways of defining it: 1)first
When do you use ‘self’ in Python? [duplicate]
This question already has answers here: What is the purpose of the `self` parameter? Why is it needed? (26 answers) Closed 6 months ago. Are you supposed to use self when referencing a member function in Python (within the same module)? More generally, I was wondering when it is required to use self, not just for methods but for variables
