Write a Python code snippet to swap the values of two variables without using a temporary variable.相关知识点: 试题来源: 解析 a, b = b, a 在Python中,可以使用元组解包的方式直接交换两个变量的值,无需临时变量。Python的赋值语句右侧会先计算出所有表达式的值,生成一个元组(b, a),然后依次赋值给...
Swap Two Values Using a Temporary Variable in Python In this method, a temporary variable is used to swap two values. Consider two variables,aandband a temporary variable,temp. First, the value ofawill be copied totemp. Then the value ofbwill be assigned toa. Lastly, the value oftempwill...
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 ...
如何使用Python交换两个变量? 在编程中,我们经常需要交换两个变量的值。在Python中,有多种方法可以实现这个目标。本文将介绍三种常用的方法。 阅读更多:Python 教程 方法一:使用临时变量 这是一种最简单的方法,它使用一个额外的变量来存储一个变量的值,然后将它

Swap variables In Python, you can swap the values of two variables in a single line. Syntax: var1, var2 = var2, var1 Example: >>> x = 10 >>> y = 20 >>> print(x) 10 >>> print(y) 20 >>> x, y = y, x >>> print(x) ...
It is often useful to swap the values of two variables. With conventional assignments, you have to use a temporary variable. For example, to swap a and b: >>> temp =a>>> a =b>>> b = temp This solution is cumbersome; tuple assignment is more elegant: ...
