How to unzip gz file using Python
提问by Darkdeamon
I need to extract a gz file that I have downloaded from an FTP site to a local Windows file server. I have the variables set for the local path of the file, and I know it can be used by GZIP muddle.
我需要将我从 FTP 站点下载的 gz 文件解压缩到本地 Windows 文件服务器。我为文件的本地路径设置了变量，我知道 GZIP 可以使用它。
How can I do this? The file inside the GZ file is an XML file.
我怎样才能做到这一点？GZ 文件中的文件是一个 XML 文件。

Maybe you want pass it to pandas also.
也许你也想把它传递给熊猫。
with gzip.open('features_train.csv.gz') as f:
features_train = pd.read_csv(f)
features_train.head()

Not an exact answer because you're using xml data and there is currently no pd.read_xml()function (as of v0.23.4), but pandas (starting with v0.21.0) can uncompress the file for you! Thanks Wes!
不是一个确切的答案，因为您使用的是 xml 数据并且目前没有pd.read_xml()功能（从 v0.23.4 开始），但是 pandas（从 v0.21.0 开始）可以为您解压缩文件！谢谢韦斯！
import pandas as pd
import os
fn = '../data/file_to_load.json.gz'
print(os.path.isfile(fn))
df = pd.read_json(fn, lines=True, compression='gzip')
df.tail()

If you are parsing the file after unzipping it, don't forget to use decode()method, is necessary when you open a file as binary.
如果您在解压后解析文件，请不要忘记使用decode()方法，当您以二进制文件打开文件时，这是必要的。
import gzip
with gzip.open(file.gz, 'rb') as f:
for line in f:
print(line.decode().strip())
