Comment by David Z on Producing all groups of fixed-length combinations
(sorry I just saw this) I don't think that's legally valid; CC-BY-SA requires that any derivative works also be shared under the same license, but I can't contribute the code to more-itertools unless...
View ArticleComment by David Z on For loop in c# vs For loop in python
FWIW here is Python's integer implementation. It essentially stores a length (ob_size, a general-purpose field that's being slightly abused for integers) and a block of uint32_t of that length, whose...

@Eatsamulhaq I'd suggest making that its own separate question, but try searching first, someone may already have asked it.
View ArticleComment by David Z on Update Git submodule to latest commit on origin
@GabrielStaples Can I ask, why did you change the git pull command to include an explicit remote and branch? Does that make a difference in what the command does?

@tcglezen That's using a different definition of "work" that was not part of the question.

I don't think this is the way to go. a = bar.A and a = bar.A() are both perfectly valid Python statements to include at that point in the code, with different meanings, and you shouldn't have to change...
View ArticleComment by David Z on pip install pyqt5, it cannot go on
I found this not to be the case: I was able to run the command from ninjaphysics' answer on Linux and it completed with no problems. Maybe it depends on the pip version? (Also, I don't think the...

View ArticleAnswer by David Z for Why does the filepath become invalid when in reality it...
Python interprets \t in a string as an escape code for a tab character. However, \l has no such special interpretation so it gets interpreted as a backslash plus l.To fix this, I suggest using raw...
View ArticleAnswer by David Z for C++ error question: Expected Unqualified-id
This probably comes from the word String in the arguments to your main() function. There is no class, function, variable, etc. named String known to the compiler, so it gives an error. You'll probably...

No, this is not possible, at least not directly in the way you're talking about it. Each instance has an independent set of instance variables, so there's no central place where you can set or change a...
