How to switch position of two items in a Python list?

You can switch the positions of two items in a Python list by simply swapping their positions. Here's how you can do it:

my_list = [1, 2, 3, 4, 5] # Index of the items to be swapped index1 = 1 index2 = 3 # Swap the items my_list[index1], my_list[index2] = my_list[index2], my_list[index1] print("List after swapping:", my_list)

This will output:

List after swapping: [1, 4, 3, 2, 5]

In this example, my_list[index1], my_list[index2] = my_list[index2], my_list[index1] simultaneously swaps the items at positions index1 and index2. This is a concise way of swapping elements in Python.

Examples

  1. Python swap positions of two elements in list

    Description: Users may search for this query when they want to interchange the positions of two elements in a Python list.

    # Python code to swap positions of two elements in a list my_list = [1, 2, 3, 4, 5] index1, index2 = 1, 3 my_list[index1], my_list[index2] = my_list[index2], my_list[index1] print(my_list)

    This code swaps the elements at positions index1 and index2 in the list my_list.

  2. Python swap elements in list by index

    Description: Users might use this query to find a way to exchange the positions of elements in a Python list based on their indices.

    # Python code to swap elements in a list by index my_list = [10, 20, 30, 40, 50] index1, index2 = 2, 4 my_list[index1], my_list[index2] = my_list[index2], my_list[index1] print(my_list)

    This code exchanges the elements at positions index1 and index2 in the list my_list.

  3. Python exchange positions of elements in list

    Description: This query indicates users are looking for a method to exchange the positions of elements within a Python list.

    # Python code to exchange positions of elements in a list my_list = ['a', 'b', 'c', 'd', 'e'] index1, index2 = 0, 3 my_list[index1], my_list[index2] = my_list[index2], my_list[index1] print(my_list)

    This code swaps the elements at positions index1 and index2 in the list my_list.

  4. Python move items in list to different positions

    Description: Users may search for this query when they want to move items within a Python list to different positions.

    # Python code to move items in a list to different positions my_list = ['apple', 'banana', 'cherry', 'date'] index1, index2 = 1, 3 my_list.insert(index1, my_list.pop(index2)) print(my_list)

    This code moves the item at position index2 to position index1 within the list my_list.

  5. Python rearrange elements in list

    Description: This query suggests users are interested in rearranging elements within a Python list.

    # Python code to rearrange elements in a list my_list = ['red', 'green', 'blue', 'yellow'] index1, index2 = 0, 2 my_list[index1], my_list[index2] = my_list[index2], my_list[index1] print(my_list)

    This code swaps the elements at positions index1 and index2 in the list my_list.

  6. Python switch positions of items in list

    Description: Users might use this query to find information on how to switch the positions of items within a Python list.

    # Python code to switch positions of items in a list my_list = ['cat', 'dog', 'rabbit', 'hamster'] index1, index2 = 1, 3 my_list[index1], my_list[index2] = my_list[index2], my_list[index1] print(my_list)

    This code swaps the elements at positions index1 and index2 in the list my_list.

  7. Python swap list elements

    Description: Users may search for this query to learn how to swap elements in a Python list.

    # Python code to swap elements in a list my_list = [100, 200, 300, 400, 500] index1, index2 = 2, 4 my_list[index1], my_list[index2] = my_list[index2], my_list[index1] print(my_list)

    This code exchanges the elements at positions index1 and index2 in the list my_list.

  8. Python interchange positions of list elements

    Description: This query indicates users want to interchange the positions of elements within a Python list.

    # Python code to interchange positions of list elements my_list = ['one', 'two', 'three', 'four', 'five'] index1, index2 = 0, 4 my_list[index1], my_list[index2] = my_list[index2], my_list[index1] print(my_list)

    This code swaps the elements at positions index1 and index2 in the list my_list.

  9. Python move elements in list to new positions

    Description: Users might use this query when they want to move elements within a Python list to new positions.

    # Python code to move elements in a list to new positions my_list = [11, 22, 33, 44, 55] index1, index2 = 2, 3 my_list.insert(index1, my_list.pop(index2)) print(my_list)

    This code moves the element at position index2 to position index1 within the list my_list.

  10. Python reorder list elements

    Description: Users may be looking for a way to reorder elements within a Python list.

    # Python code to reorder list elements my_list = ['January', 'February', 'March', 'April', 'May'] index1, index2 = 1, 3 my_list[index1], my_list[index2] = my_list[index2], my_list[index1] print(my_list)

    This code swaps the elements at positions index1 and index2 in the list my_list.
