The file argument defaults to sys.stdout (standard out), so overriding it will output to a different pipe instead. You should choose a different name. –William Jackson Mar 27 '15 at 19:44 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote accepted Ha, this already Notes Python 2 Python 3 ① zip(a, b, c) list(zip(a, b, c)) ② d.join(zip(a, b, c)) no change In the simplest form, you can get the old behavior of the zip() Posting homework assignments is not prohibited if you show that you tried to solve it yourself. this content
How to decline a postdoc interview if there is some possible future collaboration? To enable this fix, specify -f wscomma on the command line when you call 2to3. import constants ② from mbcharsetprober import MultiByteCharSetProber from .mbcharsetprober import MultiByteCharsetProber When you need to import an entire module from elsewhere in your package, use the new from . Notes Python 2 Python 3 ① u'PapayaWhip' 'PapayaWhip' ② ur'PapayaWhip\foo' r'PapayaWhip\foo' Unicode string literals are simply converted into string literals, which, in Python 3, are always Unicode.
How to reply? In Python 2, when modules within a package need to reference each other, you use import foo or from foo import Bar. In Python 2, you could redirect the output to a pipe—like sys.stderr—by using the >>pipe_name syntax.
Notes Python 2 Python 3 ① a_dictionary.keys() list(a_dictionary.keys()) ② a_dictionary.items() list(a_dictionary.items()) ③ a_dictionary.iterkeys() iter(a_dictionary.keys()) ④ [i for i in a_dictionary.iterkeys()] [i for i in a_dictionary.keys()] ⑤ min(a_dictionary.keys()) no change 2to3 errs You can manually change xreadlines() to readlines() to get it to work in Python 3. (The readlines() method now returns an iterator, so it is just as efficient as xreadlines() was Basically, I want to take over the right-click (context) menu from MSHTML. https://github.com/scholrly/neo4django/issues/236 All your urllib2 favorites—the build_opener() method, Request objects, and HTTPBasicAuthHandler and friends—are still available.
Browse other questions tagged python importerror or ask your own question. Is adding the ‘tbl’ prefix to table names really a problem? For example, if your Python 2 code imports the urllib module and calls urllib.urlopen() to fetch data, 2to3 will fix both the import statement and the function call. To do this (to the best of my knowledge), you must request the ICustomDoc interface from the control and set up your own implementation of the IDocHostUIHandler interface.
execfile statement Like the old exec statement, the old execfile statement will execute strings as if they were Python code. win32com extension help P: n/a Peter Sparago (Sorry in advance for the long post.) Hi, I'm having a great deal of difficulty buiding a Python COM extension.

Unicode raw strings (in which Python does not auto-escape backslashes) are converted to raw strings. Would we find alien music meaningful? In Python 3, the old long() function no longer exists, since longs don't exist. have a peek at these guys Declaring the metaclass in a class attribute worked in Python 2, but doesn't work in Python 3.
xrange() global function In Python 2, there were two ways to get a range of numbers: range(), which returned a list, and xrange(), which returned an iterator. throw method on generators In Python 2, generators have a throw() method. Do not do this in Python 3; the io module does it for you.
Unicode string literals Python 2 had two string types: Unicode strings and non-Unicode strings. Reddit rules These apply also on this subreddit. Whatever you want to print, pass it to print() like any other function. I had to learn it the hard way, while getting import exceptions in neo4jclient.py  and finally I gave up on rest_utils.py .
Proofread your answers for clarity and correctness. It couldn't be called or instantiated directly, but you could pass it to the global isinstance() function to check whether an object was either a Unicode or non-Unicode string. My code however does not use my own module, here is the code: import PIL from PIL import ImageGrab import numpy img = ImageGrab.grab() imgLoad = img.load() size = img.size() And check my blog C# TBB updating metadata value What is the point of update independent rendering in a game loop?
print statement In Python 2, print was a statement. reduce() global function In Python 3, the reduce() function has been removed from the global namespace and placed in the functools module.
