根据Python文档:
ZipFile.extract(member [,path [,pwd]]) 将成员从存档中提取到当前工作目录;成员必须是其全名或ZipInfo对象)。它的 尽可能准确地提取文件信息。的路径 指定要提取到的其他目录。会员可以是 filename或ZipInfo对象。 pwd是用于加密的密码 文件。
我有大量的压缩文件,每个文件包含1000个存档文件。使用上面的函数,我只能从每个压缩存档中提取我需要的文件:
def getAIDlist(aidlist_to_keep,ifile,folderName):
archive = zipfile.ZipFile(ifile) #
aidlist=archive.namelist() # gets the names of all files in the zipped archive
print "AIDs to keep",aidlist_to_keep
print "Number of AIDs in the zipped archive ",len(aidlist)
path='/2015/MyCODE/'+folderName
for j in aidlist_to_keep:
for k in aidlist:
if j in k:
try:
archive.extract(k,path)
except:
print "Could Not Extract file ",(j)
pass
return
if __name__ == '__main__':
getAIDlist(['9593','9458','9389'],"0009001_0010000.zip","TestingFolder")
理想情况下,我希望将提取的文件存储到TestingFolder
中,而是将它们存储在0009001_0010000.zip
内新创建的文件夹TestingFolder
中。
如何将提取的文件直接导入TestingFolder
但不创建新文件夹0009001_0010000.zip
?

您可以使用ZipFile.open()
而不是使用extract()
,并将文件复制到您自己选择的文件名中;使用shutil.copyfileobj()
有效地复制数据:
import shutil
archive = zipfile.ZipFile(ifile)
path = os.path.join('/2015/MyCODE', folderName)
for name in aidlist_to_keep:
try:
archivefile = archive.open(name)
except KeyError:
# no such file in the archive
continue
with open(os.path.join(path, name), 'wb') as targetfile:
shutil.copyfileobj(archivefile, targetfile)
