I've created a subclass of Python's builtin dictionary dict. The subclass allows dictionaries to have multiple keys with the same value. Hence the name "homogeneous". Behind the scenes, I'm using a normally dictionary. If a key has more than one value, then it's values are implemented with a list...
The first code review of this code can be found here:

After the bugs and points made by @Deduplicator (thank you) the code has changed significantly enough that a subsequent review is needed. Hopefully more people can help me out by providing input.

My colleagues noticed a few unorthodox ways I am writing the JavaScript code and I'd like to get the community's opinion on that.

The script I've written is able to scrape name, address, phone and web address from a webpage using python and selenium.

I am writing a .NET library and have a lot of properties like this:
public ??? SomeProperty { get; set; }
where valid values are 0-15 (or from 00000000 to 00001111 in binary). So I should choose a proper type of the property. I see two options:
byte
I can use byte and insert value validation...

In a recent code review, a work colleague and I have been discussing for the last very intense 30 minutes a very silly discussion for which we seek clarification. I argue that when iterating over a list and deciding between two values, the pythonic way should be:

Recently at work I came across this code (this is a contrived example, but is fundamentally doing the same thing):

int main()
{
A a;
a.foo = 1000;

The following code converts a number into Indian numbering system format.
I know locale can also help in getting similar format but I wanted something that can work on any system because not all locales are present in all OSs.
The code was written for Python 3.5 hence no variable annotations.

Write a program that does the following in order:
1. Asks the user to enter a number “x”
2. Asks the user to enter a number “y”
3. Prints out number “x”, raised to the power “y”.
4. Prints out the log (base 2) of “x”.
So the structure is {{Dog,Cat,Human},{Human,Dog,Whale,rabbit,Cow},{Monkey,Human,Dog}}.
Output should be: Dog,Human.
