Readability: For complex decorators, encapsulating logic in a class can make the code more organized and easier to understand. Example of a stateful decorator: class CallCounter: def __init__(self, function): self.function = function self.count = 0 def __call__(self, *args, **kwargs):...

It might get some data, and it might store data back into memory. And after it's done, the ALU is going to go back, and the program counter is going to increase by 1, which means that we're going to go to the next sequence in the instruction set. And it just goes linearly inst...
In this example, thecountersdictionaryis used to keep track of the number of function calls. After you callfoo(), the counter has increased to2as expected. All becausedictis mutable. Keep in mind, this is onlysimulatespointer behavior and does not directly map to true pointers in C or C+...
Procedure- A unit of code defined outside of the main execution code. A procedure will not be executed unless it is invoked by the main execution code or another procedure. To learn how to use procedures in VBScript, we need to pay attentions in the following areas: ...
If the items in a tuple are mutable, then you’ll be able to change them even if the tuple itself is immutable. In other words, the immutability of Python tuples refers to the references it directly holds. It doesn’t extend to the referenced objects themselves. In general, putting mutab...
Summation: After comparing all positions, the counter’s value represents the Hamming Distance. It signifies the total number of positions at which the two strings differ. Mathematically, Hamming distance is expressed as: Hamming Distance = Σ (strOne[i] ≠ strTwo[i]) here,Hamming Distance denot...
