I've been using BeautifulSoup with some success so far but every once and a while (though quite rarely), I run into a page where ...

It doesn't have to b...
I've got multiple python processes (typically 1 per core) transforming large volumes of data that they are each reading from dedicated sources, and writing to a single output file that each opened in append mode. Is this a safe way for these programs to work? Because of the tight performance requirements and large data volumes I don't ...

I am using jsonpickle to serialize an object to json. The object has certain fields that point to other objects. I'd like to selectively not include those in the serialization, so that the resulting json file is essentially pure human-readable text without any funny representations of objects. Is there a way to make jsonpickle ignore cer...
Say that I have two figures in matplotlib, with one plot per figure: import matplotlib.pyplot as plt f1 = plt.figure() plt.plot(range(0,10)) f2 = plt.figure() plt.plot(range(10,20)) Then I show both in one shot plt.show() Is there a way to show them separately, i.e. to show just f1? Or better: how can I manage the figures separat...
Hi everyone, i'm starting to learn Qt for python and as i was wondering after reading this post : qt - pyqt QTableView not populating when changing databases. if there was a way to use SQLAlchemy sessions instead of (re-)opening a database connection as a Table Model with Qt's QTableView widget.

I made this function for drawing 2D textures as images in a 2D view in my OpenGL application. After doing some testing I found that it takes up...

In some Python (v3) code I am creating lists of Decimals from user input, like this: input = [] # later populated with strings by user with values like '1.45984000E+001' decimals = [Decimal(c) for c in input] However, sometimes the input list contains strings that cannot be parsed. How can I test if c can be represented as a decimal b...
