Tuples in Pythonare immutable and we cannot sort a tuple directly. However, we can use a list to create a sorted tuple from a given tuple. For this, we will use the following steps. First, we willconvert the tuple into a listusing thelist()function. Thelist()function takes the tuple...
print("This is the main function.") hello() <^>main()<^> 1. 2. 3. 4. 5. 6. 7. 8. 此时,我们可以运行我们的程序: python hello.py 1. 我们将收到以下输出: This is the main function. Hello, World! 1. 2. 因为我们在main()中调用了hello()函数,然后只调用了main()来运行,所以Hello...
# 实现多级排序,首先按成绩降序,再按年龄升序,最后按姓名字典序升序 import operator stuTuple = tuple( [ (98, 23, 'mike'), (97, 37, 'steve'), (92, 18, 'james'), (91, 16, 'eric'), (99, 12, 'john'), (99, 12, 'dave'), (99, 14, 'jane'), (98, 25, 'jack'), (98, ...
When sorting a list of tuples, Python sorts them by the first elements in the tuples, then the second elements, and so on. To effectivelysort nested tuples, you can provide a custom sorting key using thekeyargumentin thesorted()function. Here’s an example of sorting alist of tuplesin...

从Python2.2版本开始,排序都是稳定的,也就是说如果有两个记录他们的排序键相等,则排序前后他们的原始顺序是固定不变的。 >>> data = [('red', 1), ('blue', 1), ('red', 2), ('blue', 2)]>>> sorted(data, key=itemgetter(0))
2. Sort the List of Tuples in Python You can sort a list of tuples in Python by using thesort() method, to specify the criteria for sorting, you can use thekeyparameter with value aslambdafunction that calculates the value used for sorting. Note that this method updates the original li...
而sorted() 函数是 Python 语言的内置函数,可以用于 iterables,包括 列表(List),元组(Tuple),字典(Dict)等等。iterable 对象有一个特点,就是可以用在循环 for 语句中(例如上面例子的列表 letters,可以用在 for 语句中:for e in letters:)。 下面我们来看看不同数据类型应用 sorted() 函数的例子。需要注意的是...

1.Key Function: 从Python2.4开始,list.sort() 和 sorted() 都增加了一个 ‘key’ 参数用来在进行比较之前指定每个列表元素上要调用的函数。 例如: 区分大小写的字符串比较排序: >>> sorted("This is a test string from Andrew".split(), key=str.lower) ...
