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...
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...
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 ...
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...
