In Python, the __name__ attribute is a special built-in variable that holds the name of the current module or script. When the Python interpreter runs a script or module, it assigns the value __main__ to the __name__ variable if the script is being executed as the main program. ...

https://www.python.org/dev/peps/pep-3107/Wow, I missed quite a broad area of knowledge - not only return value annotations, but also parameter annotations. Thank you very much :)And the __annotations__ attribute is a dictionary. The key return is the one used to retrieve the value ...
However, you can change the current value of this attribute because the contained object is mutable. In this regard, your Immutable class behaves similarly to Python tuples, which are immutable by definition but can store mutable objects that you can mutate at will. Using Read-Only Properties ...
What is the significance of the @ symbol in decorators? Can a decorator modify the return value of a function, and how would that work? How does Python handle variable scope when a nested function accesses a variable from its enclosing function? Topics Python Data Analysis Derrick Mwiti Topics...
In this case, the MRO is [HybridTest, WebTest, MobileTest, BaseTest, object], and Python resolves the method in the order from left to right. Hence, the output will be: Additionally, you can access the MRO by accessing the __mro__ attribute on the class, as demonstrated in the ...
While it is true that C# allows developers to perform bitwise operations on enumerations without explicitly applying the FlagsAttribute, it is important to note that Visual Basic (VB.Net) does not provide this flexibility. Therefore, if you are exposing your types to other programming languages ...
I'll start with the first attribute: eye color. In my dictionary, I write'eye_color': 'blue'. Notice that the keys are strings, so I must use quotes. Next is the height:'height': 5.7. Next, the weight:'weight': 120.5. Next, the top vacation cities, or‘vacation_cities':['Amste...
How did Python find 5 in a dictionary containing 5.0? Python does this in constant time without having to scan through every item by using hash functions. When Python looks up a key foo in a dict, it first computes hash(foo) (which runs in constant-time). Since in Python it is requir...
