Execution of Python code with -m option or not
...etween:
python foo/bar/baz.py
and
python -m foo.bar.baz
as in the latter case, foo.bar is imported and relative imports will work correctly with foo.bar as the starting point.
Demo:

Ioc/DI - Why do I have to reference all layers/assemblies in application's entry point?
...e other references, creating a deep graph of dependencies, like this:
Because the dependency graph is deep, it means that most libraries drag along a lot of other dependencies - e.g. in the diagram, Library C drags along Library H, Library E, Library J, Library M, Library K and Library N. This ma...
How are strings passed in .NET?
...

{
strLocal = "local";
}
void Main()
{
string strMain = "main";

When data is produced and not (immediately) consum...

Asserting successive calls to a mock method
Mock has a helpful assert_called_with() method . However, as far as I understand this only checks the last call to a method.
If I have code that calls the mocked method 3 times successively, each time with different parameters, how can I assert these 3 calls with their specific parameters?
