[Tutor] StringIO and dictionaries
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?

(r"") Converting those strings to normal strings, you could easily make sure the space character (#32) is taken into account by escaping it: process= "c:\\Program\ files\\WinRar\Rar.exe" ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Can I pause, stop or reset python virtual machine

In your "virtual machine", are you asking the user for a filename? Because if you are, if you have a dialog or whatever that asks the user for a filename, that point is where the "virtual machine" waits. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
