Python copies files to a specified directory
下面为大家分享一篇python复制文件到指定目录的实例，具有很好的参考价值，希望对大家有所帮助。一起过来看看吧
周末出去爬山，照了一大堆照片回来，照片同时存储为jpg和DNG格式，我用adobe bridge将dng格式的照片中要保留的筛选出来后，就不想再对着一张张去挑jpg的照片了，于是用python写个小程序帮我挑，代码如下所示：
import os
import shutil
targetnames = os.listdir('D:\\Pictures\\照片\\2016年\\东灵山\\star')
filenames = os.listdir('D:\\Pictures\\照片\\2016年\\东灵山\\jpg')
flag=[]
for name in targetnames:
if '.DNG'==name[-4:]:
targetnames[targetnames.index(name)]=name[:-4]
flag.append(True)
else:
flag.append(False)
continue
for name in targetnames:
if flag[targetnames.index(name)]:
for sname in filenames:
if '.JPG' ==sname[-4:]:
if name==sname[:-4]:
shutil.copyfile('D:\\Pictures\\照片\\2016年\\东灵山\\jpg\\'+sname,'D:\\Pictures\\照片\\2016年\\东灵山\\fabu\\'+sname)使用了os和shutil两个模块，os.listdir用于读取目标目录中的文件名称，star文件夹中存储了我手动筛选出来的DNG格式图片，jpg文件夹中存储了所有的jpg格式图片，于是在获取到所有DNG格式图片后使用flag数组标记一下，然后循环遍历targetnames数组寻找对应名称的jpg文件，找到的话就使用shutil.copyfile复制到指定文件夹，然后就大功告成了！
