Mar 2024 · 9 min read. Data classes are one of the features of Python that, after you discover them, you are never going back to the old way. Consider this regular class: class Exercise: def __init__(self, name, reps, sets, weight): self.name = name.In Python, it's possible to import multiple classes from a module by listing the class names and separating them with commas. For example, you can import class1, class2, and class3 from the module named module_name as follows: from module_name import class1, class2, class3. Alternatively, you can use the from module_name import * …def f1(self): ... @catch_exception_decorator on top of the function is a shortcut for f1 = catch_exception_decorator(f1). Instead of doing self. class, you could also access class data from the instance, as long as you're not shadowing variables. inspect.stack () [1] [3] is the function name of the current function.
