There are functions/operators like ++, -- in C language. How to use the above function in python dataframe?
There are no ++ or -- operations in python. Instead you can use +=1 or -=1. There are other also like *=, /=, %=, **= and lot more. You can take a look at https://www.w3schools.com/python/python_operators.asp for more information.

How can I add extended operators(below). Generally speaking how can I implement such an operator (for example only one).
X+=Y
X-=Y
X*=Y
X\=Y
X%=Y
X&=Y
X**=Y
X=Y
X—=Y
X//=Y
X<<=Y
X<<=Y
By implementing, for example, __iadd__. See "Emulating numeric types" in the language reference.

I write course work and now I stops in a progrees of writing, I want to build application based on Python which can drow Flowcharts of any code(maybe not all but main languages is: Python, Pascal, c++).
On Python I know about Graphviz+Pyreverse, but this solution is only for Python code vizualization.
You already have a python solution.
For C++ use clang/llvm.
For pascal, first use a pascal → C translator, then hand it to clang.

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.
