Warning: Don’t try this at home, you might burn it down. There is no legitimate reason to do the following in the course of normal day-to-day programming. Please review the other answers to this question for more realistic alternatives. I can barely imagine why you would want to do this, but here is a way … Read more
You can use a global variable within other functions by declaring it as global within each function that assigns a value to it: globvar = 0 def set_globvar_to_one(): global globvar # Needed to modify global copy of globvar globvar = 1 def print_globvar(): print(globvar) # No need for global declaration to read value of globvar … Read more
Is there a god (i.e. a parent) object? Yes. More technically, it’s the global object that all these primitives are members of; it just happens that in the browser, the window object is the global object. > window.String === String; true Why is it bad idea to have vars/functions on a global level? Because if … Read more
For the purpose of variable scoping, files have no meaning in Go. Think of all files in a package as if they would be concatenated, which (simplified) is exactly what happens before compilation. That means: No, there is no way of scoping a variable to a file. If you need two global WaitGroups, you need … Read more
The simplest way is to just use the following {{role_path|basename}}
Update: pytest-namespace hook is deprecated/removed. Do not use. See #3735 for details. You mention the obvious and least magical option: using a fixture. You can apply it to entire modules using pytestmark = pytest.mark.usefixtures(‘big_dict’) in your module, but then it won’t be in your namespace so explicitly requesting it might be best. Alternatively you can … Read more
One way to defer initialization of global variables such as the ones you are using is to wrap them in get-functions. std::default_random_engine& getEngine() { // Initialized upon first call to the function. static std::default_random_engine engine(static_cast<unsigned int>(time(nullptr))); return engine; } std::uniform_int_distribution<unsigned int>& getRandomInt() { // Initialized upon first call to the function. static std::uniform_int_distribution<unsigned int> randomInt(1, … Read more
Yes, all members of a are guaranteed to be initialised to 0. From section 3.5.7 of the C89 standard If an object that has static storage duration is not initialized explicitly, it is initialized implicitly as if every member that has arithmetic type were assigned 0 and every member that has pointer type were assigned … Read more
