There are always some interfaces between software modules.
Do you want to copy an object? In Python, no matter whether you pass an object as a parameter or return a function value, it is a reference transfer. Let's look at a C ++ function that exchanges two numbers:
The Code is as follows:
Void swap (int a, int B){Int temp;Temp =;A = B;B = temp;}
This example is an example of reference transfer! The purpose is to ex
