Assume I have a Player Class as bellows:

class Player:

self.Team = team
self.Name = name
self.Position = position
def ToString(self):
return 'team:' + self.Team + ', name:' + self.Name + ', position:' + self.Position

Here has the code snippet which include add players into list, print players before sort, print players after sorted by player's position and name:
1

The log will print as following:

team:義大犀牛, name:胡 金 龍, position:指定打擊
team:統一7-ELEVEn, name:王 鏡 銘, position:投手
[after sorted]
team:中信兄弟, name:彭 政 閔, position:一壘手
team:Lamigo, name:王 柏 融, position:左外野手

Assume I have a number array, string array, datetime array, I would like to sort by ascendant and descendant.
Here is the code snippets for utility class:
1
2
3
4
5
6
7
| ''' reverse=False means sort by ascendant '''
def sortArrayByAsc(dataArray):
return sorted(dataArray, reverse=False)
''' reverse=True means sort by descendant '''
def sortArrayByDesc(dataArray):
return sorted(dataArray, reverse=True)
|
Test the number array:
1
2
3
4
5
6
7
| numberArray = [6, 3, 1, 2, 4, 5]
print('\n Original integer array:')
print(numberArray)
print('Sort integer array by asc:' )
print(utils.sortArrayByAsc(numberArray))
print('Sort integer array by desc:' )
print(utils.sortArrayByDesc(numberArray))
|
Test result:
Original integer array:
[6, 3, 1, 2, 4, 5]
Sort integer array by asc:
[1, 2, 3, 4, 5, 6]
Sort integer array by desc:
[6, 5, 4, 3, 2, 1]
Test the string array:
nameArray = ['Albert', 'Mandy', 'Fiona', 'Ben', 'Jules']
print('\n Original string array:')
print(nameArray)
print('Sort string array by asc:' )
print(utils.sortArrayByAsc(nameArray))
print('Sort string array by desc:' )
print(utils.sortArrayByDesc(nameArray))
Test result:
Original string array:
['Albert', 'Mandy', 'Fiona', 'Ben', 'Jules']
Sort string array by asc:
['Albert', 'Ben', 'Fiona', 'Jules', 'Mandy']
Sort string array by desc:
['Mandy', 'Jules', 'Fiona', 'Ben', 'Albert']
Test the datetime array:
import datetime
datetime1 = datetime.datetime.strptime('2015-11-11 10:10:10', '%Y-%m-%d %H:%M:%S')
datetime2 = datetime.datetime.strptime('2014-01-11 12:00:00', '%Y-%m-%d %H:%M:%S')
datetime3 = datetime.datetime.strptime('2016-02-17 11:22:00', '%Y-%m-%d %H:%M:%S')
datetimes = [datetime1, datetime2, datetime3]
print('\n Original datetime array:')
print(datetimes)
print('Sort datetime array by asc:' )
print(utils.sortArrayByAsc(datetimes))
print('Sort datetime array by desc:' )
print(utils.sortArrayByDesc(datetimes))
Test result:
Original datetime array:
[datetime.datetime(2015, 11, 11, 10, 10, 10), datetime.datetime(2014, 1, 11, 12, 0), datetime.datetime(2016, 2, 17, 11, 22)]
Sort datetime array by asc:
[datetime.datetime(2014, 1, 11, 12, 0), datetime.datetime(2015, 11, 11, 10, 10, 10), datetime.datetime(2016, 2, 17, 11, 22)]
Sort datetime array by desc:
[datetime.datetime(2016, 2, 17, 11, 22), datetime.datetime(2015, 11, 11, 10, 10, 10), datetime.datetime(2014, 1, 11, 12, 0)]
Test the unique list:
names = ['Albert', 'Mandy', 'Mandy', 'Fiona', 'Ben', 'Jules']
print('\n Original name array:')
print(names)
print('Unique name array:')
print(utils.removeDuplicateInList(names))
Test result:
Original name array:
['Albert', 'Mandy', 'Mandy', 'Fiona', 'Ben', 'Jules']
Unique name array:
['Fiona', 'Ben', 'Mandy', 'Jules', 'Albert']
