Previously, I had a problem with the interference between multiple Matplotlib figures. Finally i got tracked that to an issue that some pyplot functions do not attach to their figure instance but can be rendered in some other figure instances which are created in parallel.
I am getting this error whenever I attempt to execute my pygame code:
pygame.error: video system not initialized
I’ve read every other google source and SO thread, with nothing working.
I tried to use multiple assignment as show below to initialize variables, but I got confused by the behavior, I expect to reassign the values list separately, I mean b[0] and c[0] equal 0 as before.
Recently I’ve gone through an existing code base containing many classes where instance attributes reflect values stored in a database. I’ve refactored a lot of these attributes to have their database lookups be deferred, ie. not be initialised in the constructor but only upon first read. These attributes do not change over the lifetime of the instance, but they’re a real bottleneck to calculate that first time and only really accessed for special cases. Hence they can also be cached after they’ve been retrieved from the database (this therefore fits the definition of memoisation where the input is simply “no input”).
I am trying to parse JSON from Python. I recently started working with Python so I followed some stackoverflow tutorial how to parse JSON using Python and I came up with below code –
We developed a Chrome extension, and I want to test our extension with Selenium. I created a test, but the problem is that our extension opens a new tab when it’s installed, and I think I get an exception from the other tab. Is it possible to switch to the active tab I’m testing? Or another option is to start with the extension disabled, then login to our website and only then enable the extension. Is it possible? Here is my code:
I am trying to learn python and am making a program that will output a script. I want to use os.path.join, but am pretty confused. According to the docs if I say:
I want an idiomatic way to find the first element in a list that matches a predicate.
When I use cx_Freeze I get a keyerror KeyError: 'TCL_Library'while building my pygame program. Why do I get this and how do I fix it?
