How to implement the modification operation in the list by python

Editor to share with you how python implements the modification operation in the list. I hope you will get something after reading this article. Let's discuss it together.

Changes in the list

The modification operation is to modify it on the basis of the original list, and the add and delete operations are introduced above. here, the operations that do not change the number of elements are introduced, including sorting and reversing the list.

# sort a list of integers list1 = [9, 5, 6, 2, 7, 1, 3] # sort list1.sort () # [1, 2, 3, 5, 6, 7, 9] list1 = sorted (list1) # [1, 2, 3, 5, 6, 7, 9] # sort list1.sort (reverse=True) # [9, 7, 6, 5, 3, 2, 1] list1 = sorted (list1, reverse=True) # [9, 7, 6 5, 3, 2, 1] # specify key values to sort list1 = [('aqure, 3), (' baked, 2), ('cased, 1)] list1.sort (key=lambda xpurx [1]) # [(' cased, 1), ('baked, 2), (' ajar, 3)] # # reverse the list That is, the original list in reverse order list2 = [4, 2, 3, 1] list2 = list2 [::-1] # [1, 3, 2, 4] list2.reverse () # [1, 3, 2, 4] after reading this article, I believe you have a certain understanding of "how python implements the modification operation in the list".
