[Tutor] StringIO and dictionaries

[Necmettin Begiter]

I want to run an external python script inside my script. So here is what I 
came up with:

Print codename for testing purposes.
Define an empty dictionary.
Read the file.
Do StringIO assignments and run the code.
Get the outputs and append them to the dictionary.
Print the outputs for testing purposes.


The code:
codeOut= {}
codeErr= {}

Print codename for testing purposes:
	print codename
Note: codename is a parameter that is passed to the function for the first 
parts (keys) of codeOut and codeErr dictionaries; and it prints the given 
name (deneme in this case) correctly.

Read the file:
	localfile= open(filename,'r')
	code2run= localfile.readlines()
	localfile.close()

Do StringIO assignments and run the code:
	codOut= StringIO.StringIO()
	codErr= StringIO.StringIO()
	sys.stdout= codOut
	sys.stderr= codErr
	exec code2run
	sys.stdout= sys.__stdout__
	sys.stderr= sys.__stderr__

Get the outputs and append them to the dictionary.
	erroroutput= codErr.getvalue()
	normaloutput= codOut.getvalue()
	codeOut.append({codename:erroroutput})
	codeErr.append({codename:normaloutput})

Print the outputs (just for testing):
	print codename
	print normaloutput
	print erroroutput
	print codeOut
	print codeErr

And I get nothing. Is there something I am doing wrong? Because I have read 
the parts on dictionaries and stringio and googled, but I can't find the 
problem. Any comments, suggestions? Or could someone please tell me if there 
is something wrong with my code?
