Which name is given a function that is separated by undescore.
function_name.
And to a function like FunctionName? and what would be the right one for python and ANSI C.??
Function names like func_one are written in snake case, while functions written like FunctionOne are written in Pascal case, which is a subset of Camel case where the first letter is also uppercase.
Thanks to #abelenky for pointing out the initial error.
function_name is called a Snake Case. It is the recommended casing for Python.
See this answer for more enlightenment.

I created a class.
After that i instantiated that class by the variable name 'xyz'.
Now is there a way that I can display the name of this variable i.e. print 'xyz' inside __init__in the class??
Like #Patrick Haugh mentioned in the comments, since the right hand side of the assignment is always executed first and then the assignment is evaluated with the result of that execution there is no (easy) way for the right hand side to know what the variable name would be.
Although not good, if you absolutely need to know this piece of information you can always pass the name as a parameter...
xyz = MyClass('xyz')
I believe there is a way of solving what you are asking with Metaprogramming, but since I have not experience in that area I wouldn't dare to give you any advice

By 'true function' I mean a function that cannot be recreated with ordinary python logic. For example the append function could simply be done by creating a list one larger (through lens if you dont define that as a function) than that of the original, and then transfering the contents plus that one from a user input.
If I understand your question correctly, the answer is none. You can implement the entire specification of python, in python. It is self-hosting, as are many other languages.

There are keywords like if/in as well as operators like +/- but im looking for a list of things that are like .append
Specifically something that allows you to merge the results of two different loops. Thanks.
They are classed as methods.
Proof:
Here are all of the methods of list objects:

The Formatter class has the following public methods:

I need to know the meaning of <> in Python. In Visual Basic, it means that if we have a<>0 then a is not equal to zero.
It's the same in Python 2, it means "not equal". See documentation here.
!= can also be written <>, but this is an obsolete usage kept for backwards compatibility only. New code should always use !=.
Python 3 does not have the <> operator.

What does : mean in python? I'm learning how to program in python and the tutorial i'm using
doesn't explain what : does. I can't find what : does on the internet either. Please answer :D
In object indices (e.g. some_list[4:-1]), this is called slice notation. You use it to access parts of a list/object instead of single items. See also this question for more information.
On other statements, it is required by the syntax to introduce a new code block, like on try: or if something:
