Python – 对元组字典进行排序
在本文中，我们将对元组字典进行排序。元组字典意味着元组是字典中的值或元组是字典中的键。
示例：
{'key1': (1, 2, 3), 'key2': (3, 2, 1),.............}
or
{ (1, 2, 3):value, (3, 2, 1):value,.............}方法一：使用 sorted() 方法
使用这种方法，我们可以根据键、值和项对元组字典进行排序，我们可以使用 for 循环对元组字典中的所有元素进行排序。
语法：
To sort based on items:
for i in sorted(dictionary.items()) :
print(i, end = " ")
To sort based on keys:
for i in sorted(dictionary.keys()) :
print(i, end = " ")
To sort based on values:
for i in sorted(dictionary.values()) :
print(i, end = " ") 示例 1：
Python3
# declare a dictionary of tuple with student data
data = {'student1': ('bhanu', 10), 'student4': ('uma', 12),
'student3': ('suma', 11), 'student2': ('ravi', 11),
'student5': ('gayatri', 9)}
# sort student dictionary based on items
for i in sorted(data.items()):
print(i, end=" ")
print()
# sort student dictionary based on values
for i in sorted(data.values()):
print(i, end=" ")
print()
# sort student dictionary based on keys
for i in sorted(data.keys()):
print(i, end=" ")Python3
# declare a dictionary of tuple with student data
data = {('bhanu', 10): 'student1',
('uma', 12): 'student4',
('suma', 11): 'student3',
('ravi', 11): 'student2',
('gayatri', 9): 'student5'}
# sort student dictionary based on items
for i in sorted(data.items()):
print(i, end=" ")
print()
# sort student dictionary based on values
for i in sorted(data.values()):
print(i, end=" ")
print()
# sort student dictionary based on keys
for i in sorted(data.keys()):
print(i, end=" ")Python3
# import oOrderedDict module
from collections import OrderedDict
# declare a dictionary of tuple with student data
data = {'student3': ('bhanu', 10), 'student2': ('uma', 12),
'student4': ('sai', 11), 'student1': ('suma', 11)}
# sort student dictionary of tuple based
# on values using OrderedDict
print(OrderedDict(sorted(data.values())))
print()
# sort student dictionary of tuple based
# on items using OrderedDict
print(OrderedDict(sorted(data.items())))Python3
# import orderedDict module
from collections import OrderedDict
# declare a dictionary of tuple with student data
data = {('bhanu', 10): 'student1',
('uma', 12): 'student4',
('suma', 11): 'student3',
('ravi', 11): 'student2',
('gayatri', 9): 'student5'}
# sort student dictionary of tuple based
# on items using OrderedDict
print(OrderedDict(sorted(data.items())))输出：
(‘student1’, (‘bhanu’, 10)) (‘student2’, (‘ravi’, 11)) (‘student3’, (‘suma’, 11)) (‘student4’, (‘uma’, 12)) (‘student5’, (‘gayatri’, 9))
(‘bhanu’, 10) (‘gayatri’, 9) (‘ravi’, 11) (‘suma’, 11) (‘uma’, 12)
student1 student2 student3 student4 student5
我们也可以用键作为元组来制作一个元组字典。
示例 2：
Python程序以元组为键创建元组字典并应用 sorted()函数
Python3
# declare a dictionary of tuple with student data
data = {('bhanu', 10): 'student1',
('uma', 12): 'student4',
('suma', 11): 'student3',
('ravi', 11): 'student2',
('gayatri', 9): 'student5'}
# sort student dictionary based on items
for i in sorted(data.items()):
print(i, end=" ")
print()
# sort student dictionary based on values
for i in sorted(data.values()):
print(i, end=" ")
print()
# sort student dictionary based on keys
for i in sorted(data.keys()):
print(i, end=" ")
输出：
((‘bhanu’, 10), ‘student1’) ((‘gayatri’, 9), ‘student5’) ((‘ravi’, 11), ‘student2’) ((‘suma’, 11), ‘student3’) ((‘uma’, 12), ‘student4’)
student1 student2 student3 student4 student5
(‘bhanu’, 10) (‘gayatri’, 9) (‘ravi’, 11) (‘suma’, 11) (‘uma’, 12)
方法 2：使用 OrderedDict
OrderedDict 在用于使用 sorted() 方法对字典进行排序的集合模块中可用。
语法：
To sort based on values:
OrderedDict(sorted(dictionary.values())
To sort based on items:
OrderedDict(sorted(dictionary.items())示例 1：对元组字典进行排序的Python程序
Python3
# import oOrderedDict module
from collections import OrderedDict
# declare a dictionary of tuple with student data
data = {'student3': ('bhanu', 10), 'student2': ('uma', 12),
'student4': ('sai', 11), 'student1': ('suma', 11)}
# sort student dictionary of tuple based
# on values using OrderedDict
print(OrderedDict(sorted(data.values())))
print()
# sort student dictionary of tuple based
# on items using OrderedDict
print(OrderedDict(sorted(data.items())))
输出：
OrderedDict([(‘bhanu’, 10), (‘sai’, 11), (‘suma’, 11), (‘uma’, 12)])
OrderedDict([(‘student1’, (‘suma’, 11)), (‘student2’, (‘uma’, 12)), (‘student3’, (‘bhanu’, 10)), (‘student4’, (‘sai’, 11))])
示例 2：对元组字典进行排序的Python程序，其中元组将是字典中的键
Python3
# import orderedDict module
from collections import OrderedDict
# declare a dictionary of tuple with student data
data = {('bhanu', 10): 'student1',
('uma', 12): 'student4',
('suma', 11): 'student3',
('ravi', 11): 'student2',
('gayatri', 9): 'student5'}
# sort student dictionary of tuple based
# on items using OrderedDict
print(OrderedDict(sorted(data.items())))
输出：
OrderedDict([((‘bhanu’, 10), ‘student1’), ((‘gayatri’, 9), ‘student5’), ((‘ravi’, 11), ‘student2’), ((‘suma’, 11), ‘student3’), ((‘uma’, 12), ‘student4’)])
