使用zlib.compress可以壓縮字串。使用zlib.decompress可以解壓字串。如下
| 代碼如下 |
複製代碼 |
#coding=utf-8
import zlib s = "hello word, 00000000000000000000000000000000"
print len(s) c = zlib.compress(s)
print len(c) d = zlib.decompress(c)
print d |
示範代碼2:
| 代碼如下 |
複製代碼 |
import zlib
message = 'witch which has which witches wrist watch'
compressed = zlib.compress(message)
decompressed = zlib.decompress(compressed)
print 'original:', repr(message)
print 'compressed:', repr(compressed)
print 'decompressed:', repr(decompressed) 輸出original: 'witch which has which witches wrist watch'
compressed: 'xx9c+xcf,IxceP(xcfxc8x04x92x19x89xc5PV9H4x15xc8+xca,.Q(Ox04xf2x00D?x0fx89'
decompressed: 'witch which has which witches wrist watch' |
如果我們要對字串進行解壓可以使用zlib.compressobj和zlib.decompressobj對檔案進行壓縮解壓哦，
| 代碼如下 |
複製代碼 |
def compress(infile, dst, level=9):
infile = open(infile, 'rb')
dst = open(dst, 'wb')
compress = zlib.compressobj(level)
data = infile.read(1024)
while data:
dst.write(compress.compress(data))
data = infile.read(1024)
dst.write(compress.flush())
def decompress(infile, dst):
infile = open(infile, 'rb')
dst = open(dst, 'wb')
decompress = zlib.decompressobj()
data = infile.read(1024)
while data:
dst.write(decompress.decompress(data))
data = infile.read(1024)
dst.write(decompress.flush()) |
