# Python program to swap element of a list # Getting list from user myList = [] length = int(input("Enter number of elements: ")) for i in range(0, length): val = int(input()) myList.append(val) print("Enter values to be swapped ") value1 = int(input("value 1: ")) ...
Using the assignment operator with tuple unpacking is like a shortcut in Python. It helps you quickly swap values between variables or elements in a list, making your code shorter and easier to understand. Instead of using a temporary variable, you can directly switch values in just one line...
list.insert(pos1,second_ele) list.insert(pos2,first_ele) returnlist List=[23,65,19,90] pos1,pos2=1,3 print(swapPositions(List,pos1-1,pos2-1)) 以上实例输出结果为: [19,65,23,90] 实例3 defswapPositions(list,pos1,pos2): get=list[pos1],list[pos2] list[pos2],list[pos1]=get...

简介:本文包括python基本知识:简单数据结构,数据结构类型(可变:列表,字典,集合,不可变:数值类型,字符串,元组),分支循环和控制流程,类和函数,文件处理和异常等等。 Python基础知识点总结 一、开发环境搭建 二、基本语法元素 2.1 程序的格式框架 程序的格式框架,即段落格式,是Python语法的一部分,可以提高代码的...
Again, the number of elements in the tuple on the left of the assignment must equal the number on the right. Otherwise, you get an error. Tuple assignment allows for a curious bit of idiomatic Python. Sometimes, when programming, you have two variables whose values you need to swap. In ...
foriinlist(perm): print(i) 输出: (1,2,3) (1,3,2) (2,1,3) (2,3,1) (3,1,2) (3,2,1) 它生成 n! 如果输入序列的长度为 n,则排列。 如果想要得到长度为 L 的排列,那么以这种方式实现它。 # A Python program to print all ...
