How to import a Python class that is in a directory above?
...ithout any necessary relationship to packaging -- then you need to work on __file__ to find out the parent directory (a couple of os.path.dirname calls will do;-), then (if that directory is not already on sys.path) prepend temporarily insert said dir at the very start of sys.path, __import__, remov...
How do I find the location of Python module sources?
...
For a pure python module you can find the source by looking at themodule.__file__.

...t.
Here you can notice that the middle element (in our case, with "content__middle" class) does not have any dimensional property specified - no width, nor padding, nor margin related property at all - but only an overflow: auto; (see note 1).

Behaviour of increment and decrement operators in Python
...so far as they don't explain what happens.
To be exact, +x evaluates to x.__pos__() and ++x to x.__pos__().__pos__().
I could imagine a VERY weird class structure (Children, don't do this at home!) like this:
class ValueKeeper(object):
def __init__(self, value): self.value = value
def __s...
Are there legitimate uses for JavaScript's “with” statement?

InjectedScript._evaluateOn = function(evalFunction, object, expression) {
InjectedScript._ensureCommandLineAPIInstalled();
// Surround the expression in with statements to inject our command line API so that

Best practice: PHP Magic Methods __set and __get [duplicate]
...
While I agree with your general argument that __get and __set should not be abused for lazy accessors, it is not true that you cannot get autocompletion for them. See stackoverflow.com/questions/3814733/… on how to do that.
