![]() So if you want to write 2 variable as a CSV row you can put them in a tuple or list: writer.writerows((variable1,2))Īlso from itertools you can import zip_longest as a more flexible function which you can use it on iterators with different size. In this case since zip's arguments must support iteration you can not use 2 as its argument. Print(timeit('zip(xrange(100), xrange(100))', number=500000)) python 1 /usr/bin/env python 2 - coding: utf-8 - 3 from itertools import iziplongest python 1 Traceback (most recent call last): 2 File 'untitled.py', line 3, in 3 from itertools import iziplongest 4 ImportError: cannot import name 'iziplongest' sudo python3.Here we import only class ZipFile from zipfile module. PYTHON : importing izip from itertools module gives NameError in Python 3. from itertools import for i in izip( 1, 2, 3, a, b, c): print i python itertoolsizip. It works like the built-in function zip (), except that it returns an iterator instead of a list. Here is a benchmark between zip in Python 2 and 3 and izip in Python 2: ZipFile is a class of zipfile module for reading and writing zip files. izip () returns an iterator that combines the elements of several iterators into tuples. The zip implementation is almost completely copy-pasted from the old izip, just with a few names changed and pickle support added. In Python 3 the built-in zip does the same job as itertools.izip in 2.X(returns an iterator instead of a list). ![]()
