The print should be inside the function not outside.

And main is probably not the best name. You could call it
printFoundString or somesuch...

'main' is usually used to collect all the program driver code that you 
currently have under the if name... test. The stuff you wouldn't ever 
use if importing as a module. Your way works fine too, a main is not 
obligatory. :-)



if __name__ == '__main__':
import sys
newfile = open('outfile', 'w')
help_text = "usage: python scanfile.py STRINGTOSEARCH
IMPORTFILENAME OUTPUTFILENAME"
if '-h' in sys.argv or '--help' in sys.argv or len(sys.argv) == 0:


The last test should be == 1 since the program name will always be 
there. But in fact you need the string and file args too so it

should really be:

len(sys.argv) < 4

anything less than 4 args and your code breaks...


myString = sys.argv[1]
infile = sys.argv[2]
outfile = sys.argv[3]

This function is completely pointless, you might as well
just define the variables at the top level.


print "You awake in a haze. A crate,a door and a radio."
g1 = raw_input("Which do you choose  ")
if g1 == "CRATE" or g1 == "Crate" or g1 == "crate":

...

elif g1 =="DOOR" or g1 == "Door" or g1 == "door":
   print "You are outside"
elif g1 == "RADIO" or g1 == "Radio" or g1 == "radio":

...

g2 = raw_input("So this is NYC.Ten years after.There are a few
streets.Go west or north  ")
if g2 == "WEST" or g2 == "West" or g2 == "west":
   path2_pt1()
elif g2 == "NORTH" or g2 == "North" or g2 == "north":
   path1pt1()


The block above is at top level so Python will execute it as it reads 
the file. And at this stage pathpt1 does not exist so it fails. You need 
to move this block into a function (maybe it was intended to be part of 
the one above but you messed up the indent?). Alternatively you need to 
move the definition of pathpt1 above this block.



def path1pt1():
 print "This is where it all started. Freedom Tower. A biotech firm
called Aesthos Biotechnology. Based here."
 print "I worked there."

I believe the editor of choice on Mac OS X these days is BBEdit -
again, a bit expensive. TextMate used to be good but there are
better ones out there now. Personally, I prefer the commandline
editors, vi or vim which is already installed on Mac OS X. I haven't
used the Xcode editor before but if it's what you're comfortable
with then it's probably best to stick with it.

I don't think there is a file type of Python that you can

Just curious, why would you want to use XCode as a Python editor?

Re: [Tutor] Read from large text file, parse, find string, print string + line number to second text file.

[Nick W]

I'd suggest having the newfile open after outfile is defined also a close
statement on newfile - or use it with 'with' such as:

... and replace the last line like so:
with open(outfile, 'w') as newfile:
main(mystring, infile, newfile)

(and looking muchly improved, well done)

You can also get a Cocoa version that run in a separate Window, try
