1. sorted是python的内置函数,可以对列表(list),元祖(tuple),字典(dict)和字符串(str)进行排序,排序对象作为sorted函数的参数,使用示例如下: a_tuple =(1,3,2,4) sorted(a_list) (1,2,3,4) #返回 2. sort() 是列表类的方法,只能对列表排序。sorted()对列表排序时,有返回值;sorte()对列表排序时,...
The example sorts the nested tuples initally by their first elements, then by their second. vals.sort(key=lambda e: e[1]) By providing an anonymous function which returns the second element of the tuple, we sort the tuples by their second values. $ ./sort_elem_idx.py [(-1, 3), ...
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...
print(f'Original: {tuple_data}') # Separator print('-'*20) # Function for grabbing 2nd item from the data def sorting_tup_data(item): return item[1] # Sorting based on sorting criteria in descending order sorting = sorted(tuple_data, key=sorting_tup_data, reverse=True) print(f'Sort...
6. Use User-defined Descending Order You can use thesort()function on the list List and sorts it in descending order based on the values returned by theget_length()function. This function takes a tuple as an argument and returns the second element of the tuple. Thesort()method is used ...
#Sort a list of tuples by multiple elements in descending order If you need to sort a list of tuples by multiple elements in descending order, set thereverseargument toTruein the call to thesorted()function. main.py list_of_tuples=[(1,3,100),(3,2,75),(2,3,50)]sorted_list=sort...
如果需要将Python2中的cmp函数转换为键函数, 请查看functools.cmp_to_key()。(本教程不会涵盖使用Python 2的任何示例) sorted()也可以在元组和集合上使用, 和在列表的使用非常相似: > > >>> numbers_tuple = (6, 9, 3, 1)>>> numbers_set = {5, 5, 10, 1, 0}>>> numbers_tuple_sorted = so...
A custom key function can be supplied to customize the sort order, and the reverse flag can be set to request the result in descending order. >>> 2.参数说明 iterable 可迭代对象,如:str、list、tuple、dict都是可迭代对象(这里就不局限于list了) key 用列表元素的某个属性或函数进行作为关键字(此...
reverse flag can be set to request the result in descending order. 1. 2. 3. 4. 5. 6. 7. 8. 9. 像操作列表一样,sorted()也可同样地用于元组和集合: >>>numbers_tuple=(6,9,3,1) >>>numbers_set={5,5,10,1,0} >>>numbers_tuple_sorted=sorted(numbers_tuple) ...
