python-3.4

问题 In parsing an HTML response to extract data with Python 3.4 on Kubuntu 15.10 in the Bash CLI, using print() I am getting output that looks like this: \u05ea\u05d4 \u05e0\u05e9\u05de\u05e2 \u05de\u05e6\u05d5\u05d9\u05df How would I output the actual text itself in my application? This is the code generating the string: response = requests.get(url) messages = json.loads( extract_json(response.text) ) for k,v in messages.items(): for message in v['foo']['bar']: print("\nFoobar: %s" % (message[

问题 I can bring up a web page, no problem. I can save the webpage...as html, no problem. I need to save the webpage as mht so I can can get all the html that gets hidden without saving as mht. In researching I'm coming up with absolutely nothing as to how to save as mht using python. Like I said above I can try to save it as a mht file, using the standard coded for saving as html but that simply doesn't work...not surprised it doesn't work either, but it was worth a shot. url = 'https://www

问题 I'm using NLTK to find the concordance of a word, but I don't know how to get all the results and put them in a list or set . For example: text.concordance(word) prints just the first 25 results. 回答1: TL;DR text.concordance(lines=100) From the code, https://github.com/nltk/nltk/blob/develop/nltk/text.py#L323: def concordance(self, word, width=79, lines=25): """ Print a concordance for ``word`` with the specified context window. Word matching is not case-sensitive. :seealso: ``ConcordanceIndex

问题 So I've recently dived into OOP, and so far everything is going smooth. Whilst I have no issues per se, there's an amazing feature which I hope exists, though I cannot find any documentation on said feature. When assigning attributes to objects, I often find that I have to change attribues that are dependent upon others, say, light and darkness. Here's an example: class shade: def __init__(self, light): self.light=light self.darkness=100-light def __str__(self): return (str(self.light) + ','

问题 I'm trying to call a stored procedure on a multi-db Django installation, but am not having any luck getting results. The stored procedure (which is on the secondary database) always returns an empty array in Django, but the expected result does appear when executed in a mysql client. My view.py file from SomeDBModel import models from django.db import connection def index(request, someid): #Some related django-style query that works here loc = getLocationPath(someid, 1) print(loc) def

问题 I'm using Python 3.4.2 and PyPDF2 1.24 (also using reportlab 3.1.44 in case that helps) on windows 7. I recently upgraded from Python 2.7 to 3.4, and am in the process of porting my code. This code is used to create a blank pdf page with links embedded in it (using reportlab) and merge it (using PyPDF2) with an existing pdf page. I had an issue with reportlab in that saving the canvas used StringIO which needed to be changed to BytesIO, but after doing that I ran into this error: Traceback

问题 I've created an GUI app in PyQt, which I want to share with many people. Sometimes I get unexpected exceptions and I take it for granted - after every exception I improve my code and it gets better and better. I use a logger for recording these exceptions and special hook for PyQt silenced exceptions. My code looks like this: Logger def setLogger(level=logging.DEBUG, name="my_logger", file=join("src", "log.out")): logger = logging.getLogger(name) logger.setLevel(level) # console logger ch =

问题 I was able to successfully build cython on Ubuntu 14.04 from source as explained in this SE question/answer Compiling cython From source with icc and I downloaded the source code from here - Cython source code download. The command to compile cython is CC=icc LINKCC=icc python3.4 setup.py build I am enclosing the build log. It is STILL using gcc for linking. Here is a sample of build log.

问题 I installed Python 3.4.2 and Virtualenv 12.0.5 in my Linux Mint 17.1 Then I tried creating: $ virtualenv venv And also using --clear and/or -p /usr/bin/python3.4, always getting the messages: Using base prefix '/usr' New python executable in venv/bin/python3 Also creating executable in venv/bin/python ERROR: The executable venv/bin/python3 could not be run: [Errno 13] Permission denied Another try was: $ pyvenv-3.4 venv It gave no errors on creation, but in the venv/bin file the python3.4 is

问题 I want to be able to take a photo from a webcam in python 3 and Windows. Are there any modules that support it?
