![]() 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. It is usually not needed to use the zipimport module explicitly it is automatically used by the built-in import mechanism for sys.path items that are paths to ZIP archives. pyc) and packages from ZIP-format archives. ![]() Here we import only class ZipFile from zipfile module. Source code: Lib/zipimport.py This module adds the ability to import Python modules (. Print(timeit('zip(xrange(100), xrange(100))', number=500000)) ZipFile is a class of zipfile module for reading and writing zip files. 1st step All steps Final answer Step 1/3 Here is a modified version of the code that works with Python 3 and uses the built-in zip () function instead of itertools. This shows that itertools are fast, memory-efficient tools. Notez que passer all active tous les correcteurs par défaut. Print(timeit('list(izip(xrange(100), xrange(100)))', Python from itertools import count for number in count (start1, step2): if number > 10: break print(number) output : In the above example, it can be seen that the time taken by the map function is approximately half than the time taken by for loop. Here is a benchmark between zip in Python 2 and 3 and izip in Python 2: 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).
