In Python 3 zip returns an iterator instead and needs to be passed to a list function to get the zipped ...

Mar 19, 2015 · In this case, since the zip function accepts a list of iterables in order to return their aligned columns, zip(*p) passes all the items inside the p as arguments to zip function: Therefore, in this case, zip(*p) is equal to: zip([1,2,3],[4,5,6]) Also, note that since Python-3.5 you can use unpacking operators in a few other cases than in ...

The other great answers and comments explain well the roles of argument unpacking and zip().. As Ignacio and ujukatzel say, you pass to zip() three references to the same iterator and zip() makes 3-tuples of the integers—in order—from each reference to the iterator:

I am new to python. My requirement is to zip (with compression) all files from a source directory to a target directory. I have used following code from stackOverFlow. import zipfile, os locfile = "D:\Python\Dir_dir\Dir_dir\ABC.txt" loczip = "D:\Python\Dir_dir\Dir_dir2\ABC_TEST.zip" zip = zipfile.ZipFile (loczip, "w") zip.write (locfile) zip ...

In Python 2, zip returns a list, to avoid creating an unnecessary list, use izip instead (aliased to zip can reduce code changes when you move to Python 3). from itertools import izip as zip So that is still (2.7):

The python docs gives this code as the reverse operation of zip: >>> x2, y2 = zip(*zipped) In particular zip() in conjunction with the * operator can be used to unzip a list.

Jan 29, 2013 · For example, zip('/path/to/dir', '/path/to/file.zip'), where /path/to/dir is a directory, and /path/to/file.zip doesn't exist yet. I do not want to zip the directory itself, this makes all the difference in my case. I want to zip the files (and subdirs) in the directory. This is what I'm trying:

Apr 29, 2017 · Sorting two lists together in using python zip function. 1. Zipped lists in Python are being sorted ...

Apr 4, 2019 · Instead of using Python't built-in zipfile, you can use stream-zip (full disclosure: written by me). If you have an iterable of bytes, my_data_iter say, you can get an iterable of a zip file using its stream_zip function:

Feb 14, 2011 · The itertools library provides "iterators" for common Python functions. From the itertools docs, "Like zip() except that it returns an iterator instead of a list." The I in izip() means "iterator". Python iterators are a "lazy loaded" sequence that saves memory over regular in …
