首先是數據：

將上邊的四個數據分別寫在新建的txt文件中

1、將txt數據轉為列表

with open(‘james.txt‘) as jaf:
    data = jaf.readline() #讀取數據行
    james = data.strip().split(‘,‘)#將數據轉換為列表

with open(‘julie.txt‘) as jul:
    data = jul.readline()
    julie = data.strip().split(‘,‘)

with open(‘sarah.txt‘) as sar:
    data = sar.readline()
    sarah 
 
= data.strip().split()

with open(‘james.txt‘) as jaf, open(‘julie.txt‘) as jul,open(‘sarah.txt‘) as sar:
    data = jaf.readline() #讀取數據行
    james = data.strip().split(‘,‘)#將數據轉換為列表

    data = jul.readline()
    julie = data.strip().split(‘,‘)

    data = sar.readline()
    sarah = data.strip().split()

 
print(james)
print(julie)
print(sarah)

2、排序：原地排序 james.sort()、復制排序：james2 = james.sorted() 默認升序，降序參數 sort(reverse= True)

由於數據中有-.:, 需要進一步操作

def sanitize(listt):
    if ‘-‘ in listt:
        splitter = ‘-‘
    elif ‘:‘ in listt:
        splitter = ‘:‘
    else:
        return (listt)
    (mine, sece) 
 
= listt.split(splitter)# 分裂字符串   結合字符串
    return (mine + ‘.‘ + sece)


def returnkist(string):
    with open(string) as jaf:
        data = jaf.readline()  # 讀取數據行
        james = data.strip().split(‘,‘)  # 將數據轉換為列表
        clean_james = []
        for ja in james:
            clean_james.append(sanitize(ja))
        clean_james.sort(reverse=True)

        return clean_james

clean = returnkist(‘james.txt‘)
print(clean)

def sanitize(listt):
    if ‘-‘ in listt:
        splitter = ‘-‘
    elif ‘:‘ in listt:
        splitter = ‘:‘
    else:
        return (listt)
    (mine, sece) = listt.split(splitter)# 分裂字符串   結合字符串
    return (mine + ‘.‘ + sece)



with open(‘james.txt‘) as jaf, open(‘julie.txt‘) as jul,open(‘sarah.txt‘) as sar:
    data = jaf.readline() #讀取數據行
    james = data.strip().split(‘,‘)#將數據轉換為列表

    data = jul.readline()
    julie = data.strip().split(‘,‘)

    data = sar.readline()
    sarah = data.strip().split()
clean_james = []
for ja in james:
    clean_james.append(sanitize(ja))
clean_james.sort()
print(clean_james)

Python3 將txt數據轉換成列表，進行排序，
