The isinstance built-in is the preferred way if you really must, but even better is to remember Python’s motto: “it’s easier to ask forgiveness than permission”!-) (It was actually Grace Murray Hopper’s favorite motto;-). I.e.: This, BTW, lets the function work just fine on Unicode strings — without any extra effort!-)
TL;DR The ‘ideal’ solution (Ubuntu/Debian way):$ python -m pip uninstall pip to uninstall the new pip 10 and retain your Ubuntu/Debian-provided patched pip 8. For a system-wide installation of modules use apt wherever possible (unless you are in a virtualenv), more on it below. In older Ubuntu/Debian versions, always add –user flag when using pip outside of virtualenvs (installs into ~/.local/, default in … Read more
See this link: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pywin32. It may be of help to you. EDIT: (easy version)
It takes keyword arguments for the variables: The flask-server would have functions:
Flask is actually not an MVC framework. It is a minimalistic framework which gives you a lot of freedom in how you structure your application, but MVC pattern is a very good fit for what Flask provides, at least in the way that MVC pattern is understood today in the context of web applications (which … Read more
Something like PhantomJS may be more robust, but here’s some basic Python code to extract it the full menu: After that, you’ll want to search through the menu for the date you’re interested in. EDIT: Some overkill on my part:
You’re trying to open each file twice! First you do: and then you pass infile (which is a file object) to the open function again: open is of course expecting its first argument to be a file name, not an opened file! Open the file once only and you should be fine.[
Assuming the CSV file is delimited with commas, the simplest way using the csv module in Python 3 would probably be: You can specify other delimiters, such as tab characters, by specifying them when creating the csv.reader: For Python 2, use open(‘testfile.csv’, ‘rb’) to open the file.[
BrenBarn is correct. The error means you tried to do something like None[5]. In the backtrace, it says self.imageDef=self.values[2], which means that your self.values is None. You should go through all the functions that update self.values and make sure you account for all the corner cases.
I’m working on making a URL shortener for my site, and my current plan (I’m open to suggestions) is to use a node ID to generate the shortened URL. So, in theory, node 26 might be short.com/z, node 1 might be short.com/a, node 52 might be short.com/Z, and node 104 might be short.com/ZZ. When a … Read more
