Similar to the built-in function zip(), itertools.zip_longest will continue iterating beyond the end of the shorter of two iterables.
from itertools import zip_longest
a = [i for i in range(5)] # Length is 5
b = ['a', 'b', 'c', 'd', 'e', 'f', 'g'] # Length is 7
for i in zip_longest(a, b):

In Python 2 filter, map and zip built-in functions return a sequence. map and zip always return a list while with filter the return type depends on the type of given parameter:
>>> s = filter(lambda x: x.isalpha(), 'a1b2c3')
>>> s
'abc'
>>> s = map(lambd...
The Zip extension method acts upon two collections. It pairs each element in the two series together based on position. With a Func instance, we use Zip to handle elements from the two C# collections in pairs. If the series differ in size, the extra elements of the larger series will be ignored.
To...
To start, import the zipfile module, and set the filename.
import zipfile
filename = 'zipfile.zip'
Working with zip archives is very similar to working with files, you create the object by opening the zipfile, which lets you work on it before closing the file up again.
zip = zipfile.ZipFile(fi...
Unzipping a zip archive is done with unzip function from the utils package (which is included in base R).
unzip(zipfile = "bar.zip", exdir = "./foo")
This will extract all files in "bar.zip" to the "foo" directory, which will be created if necessary. Tilde...
Listing files in a zip archive is done with unzip function from the utils package (which is included in base R).
unzip(zipfile = "bar.zip", list = TRUE)
This will list all files in "bar.zip" and extract none. Tilde expansion is done automatically from your working directory. ...
System.IO.Compression.ZipFile.CreateFromDirectory("myfolder", "archive.zip")
Create archive.zip file containing files which are in myfolder. In example paths are relative to program working directory. You can specify absolute paths.
System.IO.Compression.ZipFile.ExtractToDirectory("archive.zip", "myfolder")
Extracts archive.zip to myfolder directory. In example paths are relative to program working directory. You can specify absolute paths.
' Create filestream to file
Using fileStream = New IO.FileStream("archive.zip", IO.FileMode.Create)
' open zip archive from stream

The zip function accepts 2 parameters of type SequenceType and returns a Zip2Sequence where each element contains a value from the first sequence and one from the second sequence.
Example
let nums = [1, 2, 3]
let animals = ["Dog", "Cat", "Tiger"]
let numsAndAnimals ...
The client first sends a request with an Accept-Encoding header that indicates it supports gzip:
GET / HTTP/1.1\r\n
Host: www.google.com\r\n
Accept-Encoding: gzip, deflate\r\n
\r\n
The server may then send a response with a compressed response body and a Content-Encoding header that specifies...
zip takes two lists and returns a list of corresponding pairs:
zip [] _ = []
zip _ [] = []
zip (a:as) (b:bs) = (a,b) : zip as bs
> zip [1,3,5] [2,4,6]
> [(1,2),(3,4),(5,6)]
Zipping two lists with a function:
zipWith f [] _ = []
zipWith f _ [] =...
The FileSystem API of Java 7 allows to read and add entries from or to a Zip file using the Java NIO file API in the same way as operating on any other filesystem.
The FileSystem is a resource that should be properly closed after use, therefore the try-with-resources block should be used.

There are a few ways to inspect the contents of a zipfile. You can use the printdir to just get a variety of information sent to stdout
with zipfile.ZipFile(filename) as zip:
zip.printdir()
# Out:
# File Name Modified Size
...
if a directory contain 2 files:
$ ls
makefile
example.txt
and makefile contain the following text
%.gz: %
gzip $<
then you can obtain example.txt.gz by typing in the shell
$ make -f makefile example.txt.gz
the makefile consist of only one rule that instruct make how to create a...
To write a new .zip file:

{
using (ZipArchive archive = new ZipArchive(zipToOpen, ZipArchiveMode.Update))

The following example will return the byte[] data of a zipped file containing the files provided to it, without needing access to the file system.
public static byte[] ZipFiles(Dictionary<string, byte[]> files)
{
