I found this example and I can't understand why it works unpredictably? I supposed it must output [1, 8, 15] or [2, 8, 22]
So, I have two very large lists of numbers l1 and l2. I'd like to multiply each element of l1 with each element of l2 without explictly creating a new list of products. Thus, I'd like a generator. This part is easy. I can just do something like
If you have a list in Python 3.7:You can turn that into a list of chunks each of length n with one of two common Python idioms:
I have the following code:What should RETURNTYPE and IMPLEMENTATION be in order to allow any client of MyObject (in this case the main() function), to iterate over the values of the m_Items map, without copying any data? It seems that this should be possible with c++11 range based for loops...
In order to avoid mutable containers / states I currently wonder what's the closest thing to construct a const STL container from some input, e.g.
I think my question is related to this, but not exactly similar. Consider this code:The output of this code is:
I am trying to create a generator that returns numbers in a given range that pass a particular test given by a function foo. However I would like the numbers to be tested in a random order. The following code will achieve this:
