python实现按日期归档文件

时间：2021-04-14 09:04:28|栏目：Python代码|点击：次

　　在工作过程中，data目录会一直接收文件，收到的文件放到一个大目录里不好判断是否漏收，也不利于检索；

　　所以写了个脚本，每天早上九点用Windows计划执行，将昨日这个文件夹内收到的文件全部归档，归档文件夹的名字就是昨天的日期，脚本及解释如下：

import os
import datetime
import shutil
 
# get file name
def get_datetime(i):
    d = str((datetime.datetime.now() - datetime.timedelta(days=i)).date()).split("-")
    timeoffile = d[0] + d[1] + d[2]
    return(timeoffile)
 
# new file
def get_newfile(i):
    filename = get_datetime(i)
    aimPath = 'C:\\data\\' + filename
    isExists=os.path.exists(aimPath)
    if not isExists:
        os.makedirs(aimPath)
        print(aimPath + 'ok!')
        return aimPath
    else:
        print(aimPath + 'file is exists!')
        return False
 
 
def delete_flie(filePath):
    for i,j,k in os.walk(filePath):
        n = 0
        while n < len(k):
            fileneed = filePath + '\\' + k[n]
            if(os.path.exists(fileneed)):
                os.remove(fileneed)
            else:
                pass
            n = n + 1
     
# get file name and move
def get_filename(filePath):
    for i,j,k in os.walk(filePath):
        n = 0
        while n < len(k):
            fileneed = filePath + '\\' + k[n]
            if(os.path.exists(fileneed)):
                shutil.move(fileneed,aimPath)
            else:
                pass   
            n = n + 1
 
# Monday special
def is_Monday():
    if datetime.datetime.now().weekday() == 0:
        return 3
    else:
        return 1
 
filePath = 'C:\\data'
pos = is_Monday()
aimPath = get_newfile(pos)
get_filename(filePath)
delete_flie(filePath)
