Testing for C object setters/getters

Asked 2021-Feb-08 at 07:05

I'm writing a Python object in C with a set of setters and getters. I want to limit the type of the variable accessed through the setters/getters, and raise a TypeError if the incorrect type is passed. For instance, class_instance.minute = "string" should raise a TypeError as minute expects an integer:

Your macro VERIFY_NUMBER isn't correct. You should use PyLong_Check, which:

Return true if its argument is a PyLongObject or a subtype of PyLongObject. This function always succeeds.

I would rewrite your macro and turn it into a new function like this:

I'm using pytest to make assertions on a value created by a function inside a class that writes to and returns an attribute of the class. The attribute value persists across two unit tests. How can I get a fresh instance of the class in the second unit test?

In Script1 I've defined class1.

To initiate class1, you just need one variable x, but it has other attribute y which is not required to initiate the class. When I run script 1, it assigns value 10 to y which is declared after if __name__ == __main__: line.

Allowing class template's template parameters to be visible in the derived class

Asked 2020-Jan-30 at 03:11

I want to preserve visibility of a class template's parameter arguments when I inherit from it. The base class will have a large number of template arguments, so I don't want to keep asking for those in the derived class templates. Is the only way to do this with type aliases?

For example, this doesn't work, but it does if I swap everything out for the commented lines:

QUESTION

Python how to get bound method of some property.setter

Asked 2019-Dec-17 at 18:37

I have a class with one property. I also have a setter for that property. How can I get the bound method for the property.setter?

Why I'm Asking

With normal methods, this is easy. One can just use class_instance.method_name.

However, I'm having a tough time figuring this out for property, since it returns a descriptor object.

Example Code

This was written with Python 3.6:

ANSWER

Answered 2019-Dec-17 at 18:37

In the documentation of Python descriptor, you can find the equivalent implementation of the property descriptor in pure Python, where the setter method simply calls the unbound method with the given object and target value:

How to select count() if there is a value but select nothing if the value is 0

Asked 2019-Mar-24 at 15:15

Im writing a booking system for a project and currently working on getting some report functionality built in. I need to return a list of all classes on todays date regardless of wether they have a booking or not.

The problem i am getting is when there are no bookings, i dont get anything back from the sql query but when there are bookings, i get the correct information. If i take the count for the bookings away from the select then everything works however i need all of this info.

ANSWER

Answered 2019-Mar-24 at 15:15

If you want also the not booking the you need a left join (outer) join

you should avoid old implicit join sintax based on where, you should use explicit join sintax and using this use left join for booking

QUESTION

How to access a class variable shadowed by an instance variable?

Asked 2019-Feb-15 at 11:46

I couldn't find a specific answer to my question. As you might know, a class in Python can have both class variables and instance variables. If a class has a class variable and an instance variable that both have the same name, how can I access both in another method of the class?

Suppose the following code. How can I access both variables myvar?

Answered 2018-Jul-18 at 07:11

class myclass:
    myvar = "class variable"

    def __init__(self):
        self.myvar = "instance variable"
        pass
    def test2(self):
        return myclass.myvar


some_class = myclass()
print(some_class.test2())

You have two compilation errors, although one of them is not visible. Firstly, you can't make a Euclidean space in the way you have tried to, with mk. I suggest changing from a structure to a def for the time being, since your structure only has one field:
