[英]Best (most “pythonic”) way to temporarily unzip a file
I need to temporarily create an unzipped version of some files. 我需要暂时创建一些文件的解压缩版本。 I've seen people do
zcat somefile.gz > /tmp/somefile
in bash, so I made this simple function in python: 我见过人们在bash中做
zcat somefile.gz > /tmp/somefile
,所以我在python中创建了这个简单的函数:
from subprocess import check_call
def unzipto(zipfile, tmpfile):
with open(tmpfile, 'wb') as tf:
check_call(['zcat', zipfile], stdout=tf)
But using zcat and check_call seems hackish to me and I was wondering if there was more "pythonic" way to do this. 但是使用zcat和check_call对我来说似乎很苛刻,我想知道是否有更多的“pythonic”方法来做到这一点。
Thanks for your help 谢谢你的帮助
gzip.open(zipfile).read()
will give you the contents of the file in a single string. gzip.open(zipfile).read()
将在单个字符串中提供文件的内容。
with open(tmpfile, "wb") as tmp:
shutil.copyfileobj(gzip.open(zipfile), tmp)
will put the contents in a temporary file. 将内容放在临时文件中。
