自定义排序函数通常用于sorted()或sort()的key参数。 示例 假设我们希望根据字母在英文字母表中的逆序进行排序: # 自定义排序函数 def reverse_alphabetical_order(char): return -ord(char) 使用自定义函数进行排序 list_of_letters = ['b', 'd', 'a', 'c'] sorted_list = sorted(list_of_letters, key...
sort可以按照字母顺序给出列表: 输入: # The planets sorted in alphabetical order sorted(planets) 输出: ['Earth', 'Jupiter', 'Mars', 'Mercury', 'Neptune', 'Saturn', 'Uranus', 'Venus'] sum可以给出求和: 输入: primes = [2, 3, 5, 7] sum(primes) 输出: 17 还有min和max函数可以返回列表...

As we can see, we’re banking on the OS library to produce a list of directories in alphabetical order. I guess that’s not always the case. To be sure, I took a peek at the os.listdir documentation, and it did not disappoint:...
digits.sort() print(digits) digits.sort(reverse=True) print(digits) >>> Here is the original list: ['bmw', 'audi', 'toyota', 'subaru'] Here is the sorted list: ['audi', 'bmw', 'subaru', 'toyota'] Here is the reverse alphabetical list: ...
#Put students in reverse alphabetical order. students.sort(reverse=True) # Display the list in its current order. print("\nOur students are now in reverse alphabetical order.") for student in students: print(student.title()) 1. 2.
In this program, we store the string to be sorted in my_str. Using the split() method the string is converted into a list of words. The split() method splits the string at whitespaces. The list of words is then sorted using the sort() method, and all the words are displayed.Share...
Strings are sorted in alphabetical order. Consider this list: ['Paul', 'john07', 'Anne2', 'K_a_t_e', 'jessi'] It becomes the following when sorted: ['Anne2', 'K_a_t_e', 'Paul', 'jessi', 'john07'] Tuples are sorted in lexicographic order. This means th...
students.sort(reverse=True) # Display the list in its current order. print("\nOur students are now in reverse alphabetical order.") for student in students: print(student.title()) sorted() vssort() sort()函数排序过后,原列表已经发生了变化。如果想保留原列表,生成一个新的列表,可以使用sorted(...
