convert integer to string
I have already >>> import string >>> from string import * but I can not still convert an integer to string >>> str(42) Traceback (most recent call last): File "", line 1, in str(42) TypeError: 'module' object is not callable >>> What is it wrong?

How I can draw the grid lines at intervals with step=1?
Hi I am trying to draw a step (or staircase) function. My points are all integers. I would like that the grid lines help to identify the limits of each line, but when I draw the grid, it is set each 5 units. How can I draw the grid lines at intervals with step=1? Thanks for your help in advance Regards Andres -- http://mail.python.org/mailman/listinfo/python-list

How can I verify if the content of a variable is a list or a string?
Hi, I'm writing a function which receive a list which elements are strings or new lists (sublists) containing strings. How can I verify if sone element of the list (which is contained in a variable) is a list or a string? I found the method isinstance(object,class) but I don't know which class should I use for.

Re: a little help
my mistake is because I have no problem to do that using Prolog which use an interpreter as Python. I thought that the variables in the main global memory space (associated with the command line environment) were kept, although the code that use it could change. As you explain me, Python behave like a compiled language: any time I make a change in the code, I have to "compile" it again, and re-run (and re-load the data). There is nothing to do. Thank you!

a little help
Hi, I am new using Python, although I have experience using other programming languages like Pascal, FORTRAN, C, Prolog, etc. I am using IDLE Editor for Python in coordination with the command line interface. My situation is the following: I am developing some code. I use the IDLE Editor to write it down. Then, I save it and import it from the command line interface, so it is already available from the prompt. Then I load (read) some data from files using that code. Let suppose that after that I make some changes in the code using again the IDLE Editor, save the program code, and…what else? The updated code is not already available from the command line interface. If I run the module, I lose the data already loaded (and it is a big amount). If I re-import it, the new code is not available Any suggestion? Thanks Andres -- http://mail.python.org/mailman/listinfo/python-list
