当我说Zip时,我指的是窗口使用的标准算法。不是档案。目前,我利用这几类人拼凑起来,把第64基地编码起来,并把它作为请求送交内部的APIC。

Answer 1

import zlib

teststr = """Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus
pretium justo eget elit eleifend, et dignissim quam eleifend. Nam vehicula nisl
posuere velit volutpat, vitae scelerisque nisl imperdiet. Phasellus dignissim,
dolor amet."""

cmpstr = zlib.compress(teststr.encode( utf-8 ))
uncmpstr = zlib.decompress(cmpstr)

fmt =  {:>8}: (length {}) {!r} 
print(fmt.format( teststr , len(teststr), teststr))
print(fmt.format( cmpstr , len(cmpstr), cmpstr))
print(fmt.format( uncmpstr , len(uncmpstr), uncmpstr))

产出:

 teststr: (length 237)  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus
pretium justo eget elit eleifend, et dignissim quam eleifend. Nam vehicula nisl
posuere velit volutpat, vitae scelerisque nisl imperdiet. Phasellus dignissim,
dolor amet.

甲型六氯环己烷有<条码>。模块允许阅读/篡改档案。

zipfile.ZipFile 班级有<代码>writestr(>)方法,可直接从地壳中产生“档案”。

因此,在存档之前,你不必写上你方言。

www.un.org/spanish/ecosoc 问询后的最新情况

你们说不希望档案,但相关的《公共卫生法》只是建立PK-Zip档案。在沙里,你与zipfile相同。这里的一个例子是,它造成了一种 ,并增加了一个档案——所有内流,没有物理档案。

import zipfile
from cStringIO import StringIO

f = StringIO()
z = zipfile.ZipFile(f,  w , zipfile.ZIP_DEFLATED)
z.writestr( name ,  some_bytes_to_compress )
z.close()

output_string = f.getvalue()

<编码>output_string将是PK-Zip格式压缩内容。

如果你控制发送和接收方,那么你就没有必要用PK-Zip高射线的一组数据发送多份压缩档案。相反,你只能使用<代码>zlib模块,用于对PK-Zip进行压缩。

import zlib

output_string = zlib.compress( some_bytes_to_compress )

And then you can decompress it (assuming Python):

decompressed_string = zlib.decompress(output_string)

I don t know it exactly what you need but you might find this interesting. I use here the zipfile module with a string-file-like object

import zipfile
import StringIO

s = StringIO.StringIO()  # s is a file like object
z = zipfile.ZipFile(s,  w )  # this is a zip archive
z.writestr( file1.txt ,  Hello, world ) # create a "file" inside the archive called  file1.txt  and write  hello world  into it
z.close() # close the archive

print s.getvalue()  # this is the content of the string
s.close()  # close the string file-like object

观察 PK从护卫开始

Answer 4

import os
import zipfile

content =  foo bar 
filename =  test.txt 
zipfile_name =  test.zip 
zipfile_path = os.path.join( /tmp , zipfile_name)
with zipfile.ZipFile(zipfile_path,  w , zipfile.ZIP_DEFLATED) as z:
    z.writestr(filename, content)
