copied!<p>I'm not sure how or if this would work on windows, but under unix, you could do something like:</p> <pre><code>import signal import sys count = 0 def handler(signum,frame): global count print "Value of 'i' is",i count += 1 if count >= 2: sys.exit(0) signal.signal(signal.SIGINT,handler) i = 0 while True: i += 1 </code></pre> <p>Here I exit the program after ctrl-C is caught (twice) because I don't have any other good way of exiting the program.</p> <p>The use of global data here is merely for demonstration purposes -- Out in the wild, I'd use a class and pass an instance-method to the signal handler in order to maintain state between calls. -- e.g., something like:</p> <pre><code>import signal class Reporter(object): def __init__(self): self.retval = [] def handler(self,signum,frame): print self.retval r = Reporter() signal.signal(signal.SIGINT,r.handler) </code></pre> <p>And then you can just re-bind <code>self.retval</code> whenever you enter/exit your function:</p> <pre><code>import os def search(path,filename): global found folders = [] retval = [] r.retval = retval #<--- Line added try: for item in os.listdir(path): if not os.path.isfile(os.path.join(path, item)): folders.append(os.path.join(path, item)) else: if item == filename: found += 1 retval.append(os.path.join(path, item)) except WindowsError,e: print str(e)[10:] for folder in folders: retval += search(folder,filename) r.retval = retval #<---- Line added return retval found = 0 path = 'C:\\' filename = 'test.txt' print search(path,filename) </code></pre> <p>I think I would prefer a non-recursive solution using <code>os.walk</code> however:</p> <pre><code>import os def search(path,filename): retval = [] r.retval = retval for (dirpath, dirnames, filenames) in os.walk(path): retval.extend(os.path.join(path,dirpath,item) for item in filenames if item == filename) return retval path = 'C:\\' filename = 'test.txt' print search(path,filename) </code></pre>
