python - Mixin class to trace attribute requests - __attribute__ recursion -

-

I am trying to create a class that others should have a superclass, tracing their property requests, Thought of using getattribute ", which attributes all the feature requests, but it generates recursive: 

  class Mixin (object): def __getattribute__ (self, attr): print I know why I get recurring: it's for myself  dict  calls that remember

> retrieve I "return item .__ getattribute __ (self, etter) "Has tried to change the last line in as suggested in other posts but the recurrence is remembered.

try this: 

  class Mixin (object): def __getattribute__ (Self, atri): print itself, "getting", attr back object .__ Getattribute __ (self, attr)

If you are still having recurring problems, The reason is that you have not shown us 

  & gt; & Gt; & Gt; Square compile (object): ... def __getattribute__ (auto, attr): ... print itself, "meet", et ... return object .__ getattribute __ (self, entree) ... & gt; & Gt; & Gt; Mixin () .__ str__ & lt; __ Main __. Mixed object at 0x00B47870 & gt; 0x00B47870 __str__ of the mixin object & lt; Method-wrapper is being '__str__' & gt; & Gt; & Gt; & Gt; Mixen (). Fauber & lt; __ Main __. Mixed object at 0x00B47670 & gt; Foobre traceback (most recent call final) is happening: file "& lt; stdin>", line 1, & lt; Module & gt; Error in the file "& lt; stdin & gt;", line 4, __getattribute__ attribute: 'feature' object, 'fiber' & gt; & Gt; & Gt;

And here's the result when Bob's code 

 > gt; & Gt; Class mylist (mix): ... def __init__ (self, list): ... if not (lista) == type (""): ... self.value = lista [...] ... def __add__ (self, some): ... back to self Price ... something ... def __getitem__ (auto, item): ... back to self Value [item] ... def __getslice__ (auto, beg, end) :. .. return self Price [Request:]] ...> gt; & Gt; A = Myलिस्ट ([1,2])> gt; & Gt; & Gt; A.value & lt; __ Main __. Mylist object 0x00B47A90 & gt; Getting the price [1, 2]

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).
