Re: [Tutor] Exec function problem

"Currall, Andrew" <andrew.curr...@aecom.com> wrote

DemandModel.py is a valid, working python script. 
If I create another script file, then:

execfile('DemandModel.py')

You probably shouldn't. You should probably be importing it. 
Is there a reason why you want to use execfile()? 
Its nearly always the wrong solution...

def runfile():
    execfile('DemandModel.py')

runfile()

  File "DemandModel.py", line 12, in DemandModel
    Parameters=ReadDmData(segname)
NameError: global name 'ReadDmData' is not defined

So it works on a line by itself but not in a function?
And it is running the file but getting an undefined name. odd.
What happens if you run execfile() from a new interpreter prompt?

CodeFile=open('DemandModel.py', 'r')
exec(CodeFile)

What happens if you use import (assuming you store in 
somewhere in sys.path...)
