文件分类的一般流程
# 1,需要处理的文件 # 2.创建保存文件的列表 # 3.写入文件 # 4.关闭文件
事例一.
QQlist=[5,6,7,8,9,10,11,"小垃圾"] filepath = r"G:我的pythonpython基础day12QQQQGood.txt" file = open(filepath,"rb") mylist = file.readlines() file.close() # 创建文件对象 存放到列表中 filelist=[] for i in QQlist: QQfilepath = "G:\我的python\python基础\day12\QQ\QQ位数分类\"+str(i)+"位QQ.txt" QQfile = open(QQfilepath,"wb") filelist.append(QQfile) # 分类位置 for line in mylist: bakline = line line = line.decode("utf-8") linelist = line.split("----") length = len(linelist[0]) # 取账号的长度 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) # 关闭文件 for QQfile in filelist: QQfile.close()
事例二
import codecs # 1,需要处理的文件 filepath = r"G:我的python尹成python基础day12kaifangkaifangGood.txt" file = codecs.open(filepath,"rb","utf-8","ignore") mylist = file.readlines() file.close() print("内存加载结束,准备区域划分") # 2.创建保存文件的列表 area = [ age for age in range(1000,2018)] length = len(area) areafilelist = [] for data in area: areafilepath = "G:\我的python\尹成\python基础\day12\kaifang\年龄\" + str(data) + ".txt" areafile = open(areafilepath,"wb") areafilelist.append(areafile) # 3.写入文件 for line in mylist: linelist = line.split(",") chstr = linelist[1][6:10] # 取出一个字符 for i in range(length): if str(area[i]) == chstr: areafilelist[i].write(line.encode("utf-8")) # 4.关闭文件 for data in areafilelist: data.close()
事例三 (按照身份证号码取)
import codecs filepath = r"G:我的pythonpython基础day12kaifangkaifangGood.txt" file = codecs.open(filepath,"rb","utf-8","ignore") mylist = file.readlines() file.close() print("内存加载结束,准备区域划分") # 分类器 area=[[11,"北京"],[12,"天津"],[13,"河北"],[14,"山西"],[15,"内蒙古"],[21,"辽宁"],[22,"吉林"],[23,"黑龙江"],[31,"上海"],[32,"江苏"],[33,"浙江"],[34, "安徽"],[35,"福建"],[36,"江西"],[37,"山东"],[41,"河南"],[42,"湖北"], [43, "湖南"],[44,"广东"],[45,"广西"],[46,"海南"],[50,"重庆"], [51, "四川"],[52,"贵州"],[53,"云南"],[54,"西藏"],[61,"陕西"], [62, "甘肃"],[63,"青海"],[64,"宁夏"],[65,"新疆"],[71,"台湾"], [81, "香港"],[82,"澳门"]] length=len(area)#长度 # 创建区域文件的对象 areafilelist = [] for data in area: kffilefath = "G:\我的python\python基础\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 # 判断身份证所在的地区 for i in range(length): if str(area[i][0]) == chstr: areafilelist[i].write(line.encode("utf-8")) break # 关闭文件 for line in areafilelist: line.close() length=len(area)#长度 # 创建区域文件的对象 areafilelist = [] for data in area: kffilefath = "G:\我的python\尹成\python基础\day12\kaifang\区域\" + data[1] + ".txt" kffile = open(kffilefath,"wb") areafilelist.append(kffile) # 分类写入数据 for line in mylist: linelist = line.split(",") # 字符串切割 chstr = linelist[1][0:2] # 取出2个字符 # 判断身份证所在的地区 for i in range(length): if str(area[i][0]) == chstr: areafilelist[i].write(line.encode("utf-8")) break # 关闭文件 for line in areafilelist: line.close()
