To sort a list of strings in descending or reverse order, you can pass the reverse=True argument to the sort() method or sorted() function. Descending order is the opposite of ascending order where elements are

sorted()是python的内置函数,并不是可变对象(列表、字典)的特有方法,sorted()函数需要一个参数(参数可以是列表、字典、元组、字符串),无论传递什么参数,都将返回一个以列表为容器的返回值,如果是字典将返回键的列表。 >>> mystring="54321" >>> mytuple=(5,4,3,2,1) >>> mylist=[5,4,3,2,1] >...
In Python, sorting data structures like lists, strings, and tuples can be achieved using built-in functions likesort()andsorted(). These functions enable you to arrange the data in ascending or descending order. This section will provide an overview of how to use these functions. Thesorted()...
If you have any keys you’d recommend, let us know in the comments. As it turns out, manipulating strings isn’t always easy. I learned that the hard way when I started the Reverse a String in Every Language series.Sort a List of Strings in Python in Descending Order...

Just like before, you can use sorted() to iterate through each element of the iterable you pass in. In a string, each element means each character, including spaces. Note: Python sorts strings lexicographically by comparing Unicode code points of the individual characters from left to right. ...
