list.sort()和sorted()都有一个boolean类型的reverse参数,可以用来指定升序和降序排列,默认为false,也就是升序排序,如果需要降序排列,则需将reverse参数指定为true。 代码语言:javascript 复制 >>>sorted(student_tuples,key=itemgetter(2),reverse=True)[('john','A',15),('jane','B',12),('dave','B',...
This means that all of the objects inside a set are always going to be unique or distinct.Python集对于跟踪不同的对象和执行诸如并集、交集和集差等数学集操作特别有用。 Python sets are especially useful for keeping track of distinct objects and doing mathematical set operations like unions, intersec...
sort() >>> print(sorted_values) None >>> # Print original variable >>> print(values_to_sort) [1, 2, 5, 6] There are some pretty dramatic differences in how .sort() operates compared to sorted() in this code example: There is no ordered output of .sort(), so the assignment...
In Python, you can use the sorted() function to sort a set of values. Sets in Python, by definition, are unordered collections of unique elements. When you sort a set, the result will be a new sorted list, as sets themselves don’t have a specific order. To sort elements in ...

Tuples areimmutabledata structures in Python, similar to lists, but they are enclosed within parentheses and cannot be modified once created. Sorting tuples can be achieved using the built-insorted()function. Ascending and Descending Order
sorted_string =''.join(sorted(string_example))# returns "ehllo" Sorting Sets Sets are unordered, but you can still sort their elements using thesorted()function, which then returns a sorted list. set_example ={5,2,3,1,4} sorted_set =sorted(set_example)# returns [1, 2, 3, 4, 5...

Thesorted()function of the dictionary allows you to sort the dictionary items; here, we need to sort the dictionary based on the key, so here, use the items() with the sorted() function. Using theitems()method, first, the dictionary is converted into tuples containing key-value pairs, ...
Old stalwarts C and C++ are fairly low-level languages, used when speed is most important. Your operating system and many of its programs (including the python program on your computer) are probably written in C or C++. These two are harder to learn and maintain. You need to keep track ...
