In this step-by-step tutorial, you'll learn how to use the Python zip() function to solve common programming problems. You'll learn how to traverse multiple iterables in parallel and create dictionaries with just a few lines of code.
From Python docs, here's an approximate implementation of zip function, def zip(*iterables): sentinel = object() iterators = [iter(it) for it in iterables] while iterators: result = [] for it in iterators: elem = next(it, sentinel) if elem is sentinel: return result.append(elem) ...

(one=1, two=2, three=3) >>> b = {'one': 1, 'two': 2, 'three': 3} >>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3])) >>> d = dict([('two', 2), ('one', 1), ('three', 3)]) >>> e = dict({'three': 3, 'one': 1, 'two': 2}) >>> ...

Dictionaries can be written manually, or, if you have two lists, you can combine thedict()andzip()methods to make the lists into a dictionary. list_of_shows = ["Bojack Horseman", "My Hero Academia", "Ozark", "Arrested Development", ...
When this property is set to the value 4, WinZip AES compatible encrypted zip archives are produced. Note: Prior to Chilkat v9.4.1, other possible values for this property were: 1 (blowfish), 2 (twofish), and 3 (rijndael). These settings originally provided a way to produce strong ...
zip 的常见用法之一是同时迭代多个序列,可能结合 enumerate 使用: In [95]: for i, (a, b) in enumerate(zip(seq1, seq2)): ...: print('{0}: {1}, {2}'.format(i, a, b)) ...: 0: foo, one 1: bar, two 2: baz, three 给出一个“被压缩的”序列, zip 可以被用来解压序列。
