# 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: ")) ...
One of the easiest and most commonly used methods to swap a list of elements is through the assignment operator with tuple unpacking. 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, maki...
In this next example, we will use Python’szip() functionto swap the arrangement of the 2D list: transposed=list(zip(*original))print(transposed)# [(1, 3, 5), (2, 4, 6)] Thezip()function takes any number of iterables as arguments and returns an iterator that aggregates elements ...
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 ...

>>> # Swap the first and last elements in a list >>> numbers = [1, 2, 3, 4, 5]>>> numbers[0], numbers[-1] = numbers[-1], numbers[0]>>> numbers [5, 2, 3, 4, 1]4.颠倒序列 有时需要颠倒序列。虽然可以用for循环语句来实现，但是还有一种更简单直接的方法。与上述情况类似，...
