In C#, arguments can be passed to parameters either by value or by reference.Passing by reference enables function members, methods, properties, indexers, operators, and constructors to change the value of the parameters and have that change persist in the calling environment. To pass a paramete...
2. Arguments Immutable arguments are effectively passed “by value.” (int,string,tuple) (复制) Mutable arguments are effectively passed “by pointer.” (list, dictionary) (引用) >>>defchanger(a, b):#Arguments assigned references to objects... a = 2#Changes local name's value only... b...
Contrasting Pass by Reference and Pass by Value When you pass function arguments by reference, those arguments are only references to existing values. In contrast, when you pass arguments by value, those arguments become independent copies of the original values. Let’s revisit the C# example, th...

You can pass a function as an argument by defining two functions and passing one function as a parameter when calling the other. Syntax Consider the below syntax (or, approach) to pass a function as an argument: def func1(): body def func2(): body # Calling func2(func1) ...
