Python has two basic function for sorting lists:sortandsorted. Thesortsorts the list in place, while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandrev
下面是一个冒泡排序的实现：defbubble_sort(lst): n =len(lst)for i inrange(n):for j inrange(, n-i-1):if lst[j]> lst[j+1]: lst[j], lst[j+1]= lst[j+1], lst[j]return lstexample_list =[3,1,4,1,5,9,2,6,5,3]sorted_example = bubble_sort(example_list)print(sor...
Starting with Python 2.4, bothlist.sort()andsorted()added akeyparameter to specify a function to be called on each list element prior to making comparisons.【自从python2.4之后,list.sort和sorted都添加了一个key参数用来指定一个函数,这个函数作用于每个list元素,在做cmp之前调用】 For example, here's...
For example, if you need to store the ages of all the students in a class, you can do this task using a list. Lists are similar to arrays (dynamic arrays that allow us to store items of different data types) in other programming languages. Create a Python List We create a list by...
sort() accepts two arguments that can only be passed by keyword (keyword-only arguments): sort() 方法接受 两个参数,只能通过 keywords 进行传递。 keyspecifies a function of one argument that is used to extract a comparison key from each list element (for example, key=str.lower). The key ...

b.sort() print(b) #your solution here'''#第二种方法:结合key关键字一条就出来了sorted(my_str.split(),key=str.lower)#输出结果['an','cased','Example','Hello','Is','letters','this','With']#第三种,无视大小写排序#breakdown the string into a list of wordswords =my_str.split()#so...
To return the indices of the sorted elements, you can use thesorted()function along with theenumerate()function. Thesorted()function returns a new list of sorted elements without modifying the original list. Here is an example: # Create a list of numbersnumbers=[5,2,8,1,3]# Sort the ...
fruits.sort(key=len) # 更新后的fruits: ['pear', 'apple', 'banana', 'grape', 'mango'] # 查找指定值的索引(如果不存在则返回None) index_of_banana = fruits.index('banana') # 输出: 2 列表操作符示例: list1 = [1, 2, 3] list2 = [4, 5, 6] ...
