输入x值:2输入y值:3交换后x的值为:3交换后y的值为:2 以上实例中,我们创建了临时变量 temp ,并将 x 的值存储在 temp 变量中,接着将 y 值赋给 x,最后将 temp 赋值给 y 变量。 不使用临时变量 我们也可以不创建临时变量,用一个非常优雅的方式来交换变量: x,y=y,x 所以以上实例就可以修改为: 实例 ...
In Python, it's concise, easy andfasterto swap 2 variables compared in other Programming languages: Python: x, y = y, x Other programming languages: temp =x x=y y= temp Actually, we can also use the second method just like the other programming languages, but it's slower than the f...
// C program to swap two variables in single line #include <stdio.h> int main() { int x = 5, y = 10; //(x ^= y), (y ^= x), (x ^= y); int c; c = y; y = x; x = c; printf("After Swapping values of x and y are %d %d", x, y); return 0; } ...
Once you’ve done the swap, temp is no longer needed.Note: In Python, there’s a clean and elegant way to swap values between variables without using temporary variables. You’ll learn about this topic in the section on iterable unpacking....

Swap variablesIn Python, you can swap the values of two variables in a single line.Syntax:var1, var2 = var2, var1Example:>>> x = 10 >>> y = 20 >>> print(x) 10 >>> print(y) 20 >>> x, y = y, x >>> print(x) 20 >>> print(y) 10 >>> CopyLocal and global ...
当我们开始解析函数时，我将更详细地介绍该计算的工作原理，但本质上，每个参数和局部变量都会在该堆栈空间中获得一个槽，并增加 StackFrame.frame_size （从而增加下一个变量的偏移量） 取决于它的大小。每个参数和局部变量的偏移量、类型信息和其他数据都按声明顺序存储在 StackFrame.variables 中的 FrameVar 实例...
