You can change the destination of your compressed files by opening the app that does the compression. For entering the data use a loop: def enterList (): result while True: value rawinput () if value: result.append (value) else: return result A enterList () B enterList () For comparing you can use zip to build pairs and compare each of them: for a, b in zip (A, B): if a b: print a, '', b.

How to make zip files save somewhere else You can use a free app such asįolderWasher to remove dot files before creating the zip. The code is also available on my Github Repo. These are Mac system files and can be ignored. Create a new file with the following code on your local system. Note that Windows users decompressing your zip will also see ‘dot files’ – files and folders whose filenames are preceded by dots or sometimes underscores (such as ‘.DS_Store’ or ‘_MACOSX’). Once zipping has completed, drag the folder you created to the Trash. Then hold down Ctrl and click the folder, selecting the Compress option on the menu. Drag and drop the files you want to be in the zip, but hold down Alt before releasing the mouse button so the files are copied there. To compress several files and/or folders, create a new folder (Shift +Ĭmd + N) within Finder or on the desktop and name it whatever you want the zip to be called. It means that when we copy the objects using the copy() method instead of operator, the address of the original object and copied object are different. You can delete the original file if you wish, but you won’t be able to view or use the zipped file in its present form: you’ll need to unzip it first. When invoked on any object, the copy() method creates a new object with the same data as the original object and returns a reference to it. try: from futurebuiltins import zip except ImportError: not 2.6+ or is 3.x try: from itertools import izip as zip < 2.5 or 3.x except ImportError: pass The advantage of using futurebuiltin is that it's in effect a bit more 'explicit' as to intended behaviour of the module, supported by the language syntax, and possibly recognised by tools.

This won't matter for small sets of data, but with 800,000 of them, it all adds up.-Steven. That means zip has to convert every one of those 800,000 floats into rich Python float objects.

zip file can now be emailed to a friend or simply stored until needed. It's going to take some time to copy Python list of objects, not an array of bytes like the array module uses. I am assuming that you already have an SMTP (Simple Mail Transfer Protocol ) server setup if not you can use Gmail SMTP or something like.
