Special functions in python are the functions which are used to perform special tasks. These special functions have__as prefix and suffix to their name as we see in__init__()method which is also a special function. Some special functions used for overloading the operators are shown below: ...
Operator overloading is an essential process in OOP, which adds multiple functions to the available operators. Operator overloading is the process of extending the predefined function of an operator to user defined functions. For example, the operator + is used to add two integers, join two st...
Python does all this using special methods. These special methods have a naming convention, where the name starts with two underscores, followed by an identifier and ends with another pair of underscores. Essentially, each built-in function or operator has a special method corresponding to it. Fo...

Method overloading is only meaningful in statically types languages where the same number of arguments can have different types. In Python the type is allocated dynamically, based on the data that is passed to the function, so there can only be a single implementation. In terms of arity (num...
In this program, we overload theabsolute()function. Based on the type of parameter passed during the function call, the corresponding function is called. Example 2: Overloading Using Different Number of Parameters #include<iostream>usingnamespacestd;// function with 2 parametersvoiddisplay(intvar...

pass >>> t = Test() >>> To avoid name mangling in Pascal, use: exports myFunc name 'myFunc', myProc name 'myProc'; Free Pascal supports function and operator overloading, thus it also uses name mangling to support these features. 遇到需要名字修饰的时候,Python把这些名字改成单下划线加...
One issue to be aware of is that unlike Swift we cannot immediately fail if a synchronous overload is selected in an async function. Rust's async models allows for delayed .awaiting, which means we cannot error at the call-site. Instead we'll likely need to hook into the machinery that...
