Re: import hooks
--- Patrick Stinson [EMAIL PROTECTED] escribió: Right on, that seemed to work, thanks. This is different than sys.path_hooks though, which requires a callable or string subclass? Yes, it's different, meta_path is a generic mechanism that doesn't depend on sys.path and is tried before sys.path is traversed; the other is triggered by a special sys.path entry (like a .zip file). After some experimentation it looks like you can disallow an import by raising an import error from your meta_path hook. It seems a little weird that python will then raise a new ImportError from import.c:find_module(), but I guess the behavior is desirable.. I think you can't make an import fail completely; if your meta_path doesn't work, the next one is tried, and then the standard places (where the error is finally raised). Looks like the global name foo not defined error: sometimes it's not a global name at all, but that's where the search finally failed. -- Gabriel Genellina Gabriel Genellina Softlab SRL Tarjeta de crédito Yahoo! de Banco Supervielle.

I do not have found another Open Source Tool that generates Python code from UML better like that. Ok, that's important. If the model cannot reflect changes in the code it becomes less and less useful. I like to model the Python language metamodel himself, with it, e.g the model of the language: I need that to better understand the language constraint of the language. [...] -a class class has 0..n attributes and 0..n method Just attributes. Methods are created on-the-fly when the corresponding function attribute is retrieved from the instance. And remember that instances are not restricted to what their class define. You can add or remove any attribute (even methods!) to any instance of a user-defined class at any time. (This doesn't apply to most builtin types, but *does* apply if you inherit from it) =You're Right but I will also model that dynamic aspect . However i think it is possible and the relevant to make a static metamodel of Python, as if there was no possibility of changing dynamic an instance. But Python *is* a dynamic language. You have to capture that into the model somehow. A lot of person do not understand nothing to Python on many aspects, because there is no graphical representation of the relation of concepts : may a module have more than on class definition ? a mix of class and global fonction? etc... A graphical representation may be useful, but it must be acurate too - else people may incorrectly deduce that something can't be done because it's not expressed in the graph. Does anyone know a document that describes it already, because I think it is complicated to find this information in the documentation of Python.

However, by studying line by line, I would have to be filled into a UML model Yes, sure, it's hard to follow. As the subtitle says, it's for language lawyers :) - a class method can contains nested method, but what is the way to get a list of internal methods, without use ? Can i just write: myNestedMethodList = method.nestedMethodList Are you talking about nested functions? = Yes You can't enumerate them from outside the container function: Python is a dynamic language, those inner functions are created when the def statement is *executed*. If you have an if statement around the def, the function may not even exist. = OK, it is diffcult to model: but possible: for example, by using a composition (a method may have 0..n inner function). The dynamic aspect may be described into a UML note or constraints for example Anyway it doesn't look right. Inner functions are not attributes of the enclosing one, like local variables are not attributes of the enclosing function. -- Gabriel Genellina Los referentes más importantes en compra/ venta de autos se juntaron: Demotores y Yahoo!

I'm unsure of what you want. Do you want the print
statement, inside the Python interpreter, to page its
output? Write a function to page the output the way
you like, and assign it to sys.displayhook (see

Hi,
I am new to Python. I would like to use Python for
the specialized purpose of dynamic expressions
parsing evaluation in my C++ application.
I would like to encapsulate the expressions to be
evaluated in Python function compile that function
at runtime, somewhat as below.
Expression to eval put in Python function
def isSizeSmall(size,vol,ADV,prod):
if ( (size 1000) (vol (0.001 * ADV))
(prod==Stock)): print OK; return 10
else: print NOK; return 11
Then, I want to evaluate the PyObject returned by
Py_CompileString multiple times in my program using
the user input as the variables to the above
function.
This I tried using two different approaches - 1)
PyEval_evalCode, 2) PyObject_CallObject.
1) When using PyEval_evalCode: The function call to
PyEval_evalCode was ok, but it did not return any
output.
2) Whereas, when I used this object with
PyObject_CallObject, it failed with error as .
Any help will be great. Many thanks in advance for
your help.
Warm Regards,
Ganesh

Remember that when you execute the Python source code,
you get the function *definition*; you are not
executing the function itself.

more help now. See the docs for Extending and

Re: Can Readlines() go to next line after a Tab
(Please keep posting on this list) --- [EMAIL PROTECTED] escribió: Thanks, but this method still reads the whole line into memory. I would like to find a way for it to stop reading when it encounters a \t and then go to the next. This would be much faster. You can't avoid reading the whole line - how can you detect the end-of-line, unless you use fixed-length records? According to my tests, readlines with a regular expression is actually faster than the index method you mentioned. Here is the code testing a 25meg file with thousands of lines, Hard to believe, altough that depends on a lot of factors. Is the posted code all your testing code? If so, it doesn't look right. Write two separate functions, without side effects each (in this case, that means using a local variable for kwords). Let's call them f1 and f2, inside kw.py. Use the timeit module to measure performance instead of time.time(). Execute both functions *separately* on two *separate* Python invocations, like this: python -m timeit -s from kw import f1,f2 f1() python -m timeit -s from kw import f1,f2 f2() and see what happens. -- Gabriel Genellina __ Preguntá.
