language agnostic - Observer Design Pattern vs "Listeners" -

-

It seems that the observer design pattern described in the GOF is actually the same thing as listeners found in various toolkits. Is there any difference between the concepts, or the audience and the inspector are actually the same thing

(I am not looking for any specific computer language implementation, I only have a design point difference (if Someone). Yes, I know that there are many answers to similar questions, SOF, but they are contained in specific questions about specific languages ​​- I was looking for a design answer I do not answer any language.)

What is the word "listener" refers to the observer pattern or Not for reference, for example, "event listeners" of Java swing are part of an observer pattern implementation, whereas nets are not "trace listeners".

Framework is not unusual for assigning a different name to the authors, but pattern patterns are commonly used when discussing patterns.

In relation to the design, language and platform are often being used on the implementation of a given paradigm. As such, a particular implementation of the supervisor pattern within a given framework (which may be to use the word "listener" to describe the role of concrete observer) may be slightly different from the design described in the book of pattern .

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
