Yes, did you try this code? It looks good to me.
To open the file you have to construct the full path, e.g.
fpath = os.path.join(path, fname)
f = open(fpath)
data = f.read()
f.close()
Then you can process the data with your regex and write it back out.

Does that give you a hint?
You don't need a timer, unless you want to interrupt the user if he is
not entering anything.

[Tutor] Python N00bi - Tough Cookie
Hello All,
I want trying to write a program that searches all the files (recursively)
under a given directory in the filesystem for phone
numbers in the form of (626) 674-5901 and and then outputting all phone
numbers found in a unique format 626-674
(If several numbers have the same office code, there should be only one line
of output for that office code.)
There are following requirments
1> Search for a pattern in all files in a directory
2> Outputing the result with a unique format ( (626) 674-5901 -> 626-674 )
3> if the result has new office code (which I am guessing first 3 digits --
626) -- add to new line
if the result has office code already in the list then append
I have generated the regular expression for the pattern and have
tested it also
\([0-9]{3}\)\s[0-9]{3}-[0-9]{4}
>>> import re
>>> p = re.compile('\([0-9]{3}\)\s[0-9]{3}-[0-9]{4}')
>>> p = re.compile('\([0-9]{3}\)\s[0-9]{3}-[0-9]{4}')
>>> p
<_sre.SRE_Pattern object at 0x00C400B8>
>>> p
<_sre.SRE_Pattern object at 0x00C400B8>
>>> print p.match("")
None
>>> print p.match('(619) 223-1212')
<_sre.SRE_Match object at 0x00A3F678>
I need options to proceed after finding the match in the files.
I was thinking to find all filenames in the directory using something like
import os
path="C:\\somedirectory" # insert the path to the directory of interest
here
dirList=os.listdir(path)
for fname in dirList:
print fname
Am I thinking correct ???
~Thanks

Even simpler?
import time
start = time.time()
while time.time() - start < 30.0:
raw_input("Press Now!")
print time.time() - start

Okay! Here's a sample 30-second Adding Game using time.time()
and a while True: loop. The timing granularity isn't all that great.
Sometimes it times out 2 or 3 seconds past 30 seconds, but in
this case, it probably isn't a big deal. This has been tested with
Python 2.4.3 running on Linux kernel 2.6.15 from the vim editor!
#!/usr/bin/python
import random
import time
startNum = random.choice(range(1, 9))
score = 0
print "#"*65
print " "*14,"Welcome to the 30-second Adding Game!"
print "#"*65
print " "* 5,"Instructions:"
print " "*10,"You'll choose a number."
print " "*10,"You'll be given a starting number."
print " "*10,"Add the number you chose to the starting number,"
print " "*10,"then keep adding your number to the sum until"
print " "*10,"the timer runs out."
print " "*10,"You'll have 30 seconds."
print " "* 5,
num2add = raw_input(" Choose a number to add: ")
print raw_input(" Press when you're ready to begin.")
print "#"*65
num2add = int(num2add) # interpolation
newNum = startNum + num2add
print " Start with the number ", startNum
start = time.time()
while True:
if time.time() - start < 30.0:
answer = int(raw_input(" Enter your answer: "))
if answer == newNum:
print " That is correct! Keep going."
score = score + 5
newNum = newNum + num2add
print " Your score is ", score
else:
print " That is incorrect. Please try again."
print " Hurry! You only have %2.1f seconds left!"\
% (30 - (time.time() - start))
else:
break
print " Buzzz!!! Time's up!"
print time.time() - start
#print "\n"
print " Your total score was: ", score
Happy Programming!

Re: [Tutor] Still Can't Find Timed While Loops
Disclaimer: I can't test this while I'm at work, but using "while 1:" instead of "while time.time() - start < 30.0" would be better. In the former case if you press enter after time has run out, it won't print the time, in the latter you could potentially make a correct answer after time has run out. Example: At 29.0 you answer raw_input awaits and you wait 5 minutes, then answer. It will still run the print statement. The loop started and it doesn't matter how long you wait, because it won't evaluate that until the loop starts again. But it may alright depending on what you are trying to accomplish.

Cool snippet! So if the player is entering numbers to an adding game,
and he has to continue entering numbers for 30 seconds, then it could
be accomplished with something similar to this, right?
import time
start = time.time()
while 1:
raw_input("Press Now!")
if time.time() - start < 30.0:
print time.time() - start
else: break
Thanks! 8^D

Re: [Tutor] Still Can't Find Timed While Loops
I can't recall what your initial project was. I think it was a text adventure. I imagine that you have bigger ideas regarding timers then your current code suggests. Maybe you should investigate a time aware long-running process. Twisted Python is such a beast. While I can't recommend it's use as it's probably over your head and certainly over mine, there is some code out there for a text adventure using Twisted Python. I think the codebase is called Twisted Reality now. Luis ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
