使用zlib.compress可以压缩字符串。使用zlib.decompress可以解压字符串。如下
代码如下 | 复制代码 |
#coding=utf-8 import zlib s = "hello word, 00000000000000000000000000000000" c = zlib.compress(s) d = zlib.decompress(c) |
示范代码2:
代码如下 | 复制代码 |
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) 输出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' |
如果我们要对字符串进行解压可以使用zlib.compressobj和zlib.decompressobj对文件进行压缩解压哦,
代码如下 | 复制代码 |
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()) |
