Use Python's built-in sort function to sort in descending order. You need to pass the reverse=True parameter when calling the function. Specific steps: 1. Create a list; 2. Use the sort() function to sort in ascending order; 3. Use the sort() function to sort in descending order, passing the reverse=True parameter. Additionally, there are other sorting methods such as the sorted() function, the list.reverse() method, and the slicing notation [::-1].
Python uses sort to perform descending sorting
How to implement descending sorting:
To use Python's built-in sort
function to sort in descending order, you need to pass the reverse=True
parameter when calling the function.
Specific steps:
<code class="python"># 创建一个列表 my_list = [5, 3, 1, 2, 4] # 使用 sort() 函数进行升序排序 my_list.sort() # 使用 sort() 函数进行降序排序,传递 reverse=True 参数 my_list.sort(reverse=True)</code>
Effect:
[1, 2, 3, 4, 5]
[5, 4, 3, 2, 1]
Other sorting methods :
Python has other ways to do descending sorting, including:
Use the sorted()
function and pass reverse=True
Parameters
<code class="python">my_list = sorted(my_list, reverse=True)</code>
Use the list.reverse()
method (reverse the list)
<code class="python">my_list.reverse()</code>
Use slice notation[::-1]
(reverse iteration of the list)
<code class="python">my_list = my_list[::-1]</code>
