在Python中,重新排列表(即对列表进行排序)是一个常见的操作。以下是一些基础概念、相关优势、类型、应用场景以及可能遇到的问题和解决方法。 基础概念 列表(List):Python中的一种数据结构,可以存储任意类型的元素,并且可以随时添加、删除和修改元素。 排序(Sorting):将列表中的元素按照某种规则重新排列。
# 创建一个待排序的列表numbers=[5,2,8,1,9]# 自定义排序函数(按照升序)defascending_order(x):returnx# 使用自定义排序函数对列表进行排序sorted_numbers=sorted(numbers,key=ascending_order)# 使用内置排序函数对列表进行排序(按照降序)sorted_numbers=sorted(numbers,reverse=True)# 在原始列表的基础上进行排序...
StrList = ['fb', 'bx', 'csw', 'qb', 'qqa', 'eeeed'] 2.1 一般字典序排列,但是大写在前,小写在后!! StrList.sort() print(StrList) ##字符串列表是按照第一个字符的大小排序的 ##输出:['Fast', 'Smooth', 'fast', 'is', 'is', 'smooth'] 2.2忽略大小写,按abcd顺序 StrList.sort(ke...
my_list.sort() # this prints the ordered list print("Ordered list: ", my_list) 如果列表已经排序,那么它将在控制台中返回 None。 my_list = [6, 7, 8, 9, 10] # this will return None because the list is already sorted print(my_list.sort()) sort()方法可以接受两个可选参数,称为key...
