Python中有一个gzip模块来处理gzip文件 读取gzip文件：
|
1
2
3
4
|
import
gzip
f
=
gzip.
open
(
"tt.gz"
,
"rb"
)
# 读取一行
f.readline()
|
GZIP:压缩一个文件
import gzip
1,f_in = open('iplist','rb')
2,f_out = gzip.open('iplist.gz','wb')
3,f_out.writelines(f_in)
4,f_out.close()
5,f_in.close()
6,f = gzip.open('iplist.gz','rb')
7,f.readline()
'121.8.102.126n'
8,f.readlines()
['182.128.179.162n', '121.9.15.146n', '125.118.221.146n', '61.139.124.66n', '183.145.208.217n', '14.153.145.49n', '116.25.192.98n', '183.7.109.62n', '218.17.162.217n', '58.213.141.183n', '61.164.166.122n', '222.95.180.41n', '182.149.234.40n', '60.177.22.212n', '180.118.29.64n', '115.197.116.39n', '222.212.49.130n', '14.216.123.197n', '14.20.31.77n', '183.22.105.212n', '219.134.89.66n', '220.167.53.179n', '183.45.111.38n', '125.120.32.98n', '180.109.64.209n']
bzip2:
写gzip文件
|
1
2
3
4
5
|
import
gzip
f
=
gzip.
open
(
"tt.gz"
,
"wb"
)
# 写入一行
f.write(
"aaa"
)
f.close()
|
写bzip2文件
|
1
2
3
4
5
|
import
bz2
f
=
bz2.BZ2File(
"2.bz2"
,
"wb"
)
# 写入一行
f.write(
"xxx"
)
f.close()
|
zip文件
zip的话，其实最主要的就是打包和解包操作。 解包zip文件：
|
1
2
3
4
5
|
import
zipfile
x
=
zipfile.ZipFile(
"1.zip"
)
# 解包所有文件
x.extractall()
x.close()
|
打包所有文件：
|
1
2
3
4
5
|
x
=
zipfile.ZipFile(
"2.zip"
,
"w"
)
# 写入两个文件
x.write(
"1.bz2"
)
x.write(
"2.gz"
)
x.close()
|
操作tarfile
在我们平时的使用过程中，经常会使用tar来对整个目录进行gzip或者bzip2打包和解包。Python中有tarfile来操作这些。 举个例子，来解压一个.tar.gz文件：
import tarfile
|
1
2
3
|
t
=
tarfile.
open
(
"1.tgz"
,
"r:gz"
)
t.extractall()
t.close()
