writer.writerow expects a sequence (a tuple or list) of values to write in a single row, with one value per column in that row. What you have given it instead is a single value. Your code really should look more like: and it looks to me like most of this code should be in a big … Read more
Your file contains UTF-8 BOM in the beginning. To get rid of it, first decode your file contents to unicode. But better don’t encode it back to utf-8, but work with unicoded text. There is a good rule: decode all your input text data to unicode as soon as possible, and work only with unicode; and encode the output … Read more
On OS X you could have multiple installation of Python, so investigate it first: All within /usr/bin are built-in and all other in /usr/local/bin are external installed by Homebrew or some other package manager. If you’re using pip or pip3 from /usr/local, then you’ve to use the same Python instance, otherwise they’re different instances. Just install it via pip: or for Python 3: then run … Read more
You need to add the package containing the executable pg_config. A prior answer should have details you need: pg_config executable not found
In general, don’t do this: because, as you have correctly noticed, it’s not clear what Python version you’re installing package for. Instead, if you want to install package for Python 3.7, do this: Replace package with the name of whatever you’re trying to install. Took me a surprisingly long time to figure it out, too. The docs about it are here. Your other option … Read more
The easiest way to install Python using conda is: conda install -c https://conda.binstar.org/krisvanneste pygame Edit (03/2016): It seems like the package is unavailable, but you can use this instead: conda install -c https://conda.anaconda.org/tlatorre python Edit (01/2017) The command has changed, now you can use: conda install -c tlatorre pygame=1.9.2 Edit (07/2018) tlatorre’s repo is still … Read more
args.infile is a list of filenames, not one filename. Loop over it: Here I used os.path.splitext() to split extension and base filename so you can generate a new output filename adding 1 to the base.
from Tkinter import * imports every exposed object in Tkinter into your current namespace. import Tkinter imports the “namespace” Tkinter in your namespace and import Tkinter as tk does the same, but “renames” it locally to ‘tk’ to save you typing let’s say we have a module foo, containing the classes A, B, and C. Then import foo gives you access to … Read more
As the documentation states [docs], In user defined base classes, abstract methods should raise this exception when they require derived classes to override the method, or while the class is being developed to indicate that the real implementation still needs to be added. Note that although the main stated use case this error is the indication … Read more
Why not just do this: Python is dynamic, so you don’t need to declare things; they exist automatically in the first scope where they’re assigned. So, all you need is a regular old assignment statement as above. This is nice, because you’ll never end up with an uninitialized variable. But be careful — this doesn’t … Read more
