How to use sort in python to perform descending order

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:

# 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)

Effect:

• Ascending sort: [1, 2, 3, 4, 5]
• Descending sort:[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

  my_list = sorted(my_list, reverse=True)

• Use the list.reverse() method (reverse the list)

  my_list.reverse()

• Use slice notation[::-1] (reverse iteration of the list)

  my_list = my_list[::-1]
