Re: need an alternative to getattr()

I think you would benefit from looking at the ConfigParser module.
I haven't tried it yet, but it looks like a nice interface for writing
and reading configuration files.

 Hi,

 AIM: I have a config file that contains configuration under headings
 like this:

 heading1:
 configuration 1
 configuration 2
 heading2:
 configuration 1
 configuration 2
 ...
 ...

 i parse this file to get heading1, heading2, etc and then i want to
 call heading1.process(), heading2.process(), etc.
 What i am trying to do is: (this is not the exact code, it just
 represents what i am trying to do)

 import heading1
 import heading2
 While True:
heading = get_next_heading(file_ptr) # This func will return
 heading1, then heading2(on next call)
if heading = :
break
getattr(heading, process)(file_ptr) # The problem, as you would
 have noticed, is that the first
 # argument to getattr is a string!!

 Is there an alternatice to getattr() that will solve my problem, or is
 there another way to do it.

[Ant]

 getattr(heading, process)(file_ptr)

How about:

eval(%s.process(%s) % (heading, file_ptr))

  globals()[heading].process(file_ptr)

or

  sys.modules[heading].process(file_ptr)

but note that, unless you are checking 'heading' against a 'known
good configuration keywords' list beforehand, you are trusting the
author of the configuration file.
