文件分類的一般流程

# 1,需要處理的文件
# 2.創建保存文件的列表
# 3.寫入文件
# 4.關閉文件

事例一.

QQlist=[5,6,7,8,9,10,11,"小垃圾"]
filepath = r"G:\我的python\python基礎\day12\QQ\QQGood.txt"
file = open(filepath,"rb")
mylist = file.readlines()
file.close()

# 創建文件對象 存放到列表中
filelist=[]
for i in QQlist:
    QQfilepath = "G:\\我的python\\python基礎\\day12\\QQ\\QQ位數分類\\
 
"+str(i)+"位QQ.txt"
    QQfile = open(QQfilepath,"wb")
    filelist.append(QQfile)

# 分類位置
for line in mylist:
    bakline = line
    line = line.decode("utf-8")
    linelist = line.split("----")
    length = len(linelist[0])  # 取賬號的長度

    if length == 5:
        filelist[0].write(bakline)
    elif length == 6:
        filelist[
 
1].write(bakline)
    elif length == 7:
        filelist[2].write(bakline)
    elif length == 8:
        filelist[3].write(bakline)
    elif length == 9:
        filelist[4].write(bakline)
    elif length == 10:
        filelist[5].write(bakline)
    elif length == 11:
        filelist[6].write(bakline)
    
 
else:
        filelist[7].write(bakline)
# 關閉文件
for  QQfile  in filelist:
    QQfile.close()

事例二

import codecs

# 1,需要處理的文件
filepath = r"G:\我的python\尹成\python基礎\day12\kaifang\kaifangGood.txt"
file = codecs.open(filepath,"rb","utf-8","ignore")
mylist = file.readlines()
file.close()
print("內存加載結束，準備區域劃分")


# 2.創建保存文件的列表
area = [ age for age in range(1000,2018)]
length = len(area)

areafilelist = []
for data in area:
    areafilepath = "G:\\我的python\\尹成\\python基礎\\day12\\kaifang\\年齡\\" + str(data) + ".txt"
    areafile = open(areafilepath,"wb")
    areafilelist.append(areafile)


# 3.寫入文件
for line in mylist:
    linelist = line.split(",")
    chstr = linelist[1][6:10]  # 取出一個字符
    for i in range(length):
        if str(area[i]) == chstr:
            areafilelist[i].write(line.encode("utf-8"))


# 4.關閉文件
for data in areafilelist:
    data.close()

事例三 （按照身份證號碼取）

import codecs
filepath = r"G:\我的python\python基礎\day12\kaifang\kaifangGood.txt"
file = codecs.open(filepath,"rb","utf-8","ignore")
mylist = file.readlines()
file.close()
print("內存加載結束，準備區域劃分")

# 分類器
area=[[11,"北京"],[12,"天津"],[13,"河北"],[14,"山西"],[15,"內蒙古"],[21,"遼寧"],[22,"吉林"],[23,"黑龍江"],[31,"上海"],[32,"江蘇"],[33,"浙江"],[34, "安徽"],[35,"福建"],[36,"江西"],[37,"山東"],[41,"河南"],[42,"湖北"],
         [43, "湖南"],[44,"廣東"],[45,"廣西"],[46,"海南"],[50,"重慶"],
         [51, "四川"],[52,"貴州"],[53,"雲南"],[54,"西藏"],[61,"陜西"],
         [62, "甘肅"],[63,"青海"],[64,"寧夏"],[65,"新疆"],[71,"臺灣"],
         [81, "香港"],[82,"澳門"]]
length=len(area)#長度

# 創建區域文件的對象
areafilelist = []
for data in area:
    kffilefath = "G:\\我的python\\python基礎\\day12\\kaifang\\省份\\" + data[1] + ".txt"
    kffile = open(kffilefath,"wb")
    areafilelist.append(kffile)

for line in mylist:
    linelist = line.split(",")  # 字符串切割
    chstr = linelist[1][0:2]  # 取出月份
    # 判斷身份證所在的地區
    for i in range(length):
        if str(area[i][0]) == chstr:
            areafilelist[i].write(line.encode("utf-8"))
            break


# 關閉文件
for line in areafilelist:
    line.close()
length=len(area)#長度

# 創建區域文件的對象
areafilelist = []
for data in area:
    kffilefath = "G:\\我的python\\尹成\\python基礎\\day12\\kaifang\\區域\\" + data[1] + ".txt"
    kffile = open(kffilefath,"wb")
    areafilelist.append(kffile)

# 分類寫入數據
for line in mylist:
    linelist = line.split(",")  # 字符串切割
    chstr = linelist[1][0:2]  # 取出2個字符
    # 判斷身份證所在的地區
    for i in range(length):
        if str(area[i][0]) == chstr:
            areafilelist[i].write(line.encode("utf-8"))
            break


# 關閉文件
for line in areafilelist:
    line.close()
