Python: Get current line runtime

Question

In Python how to get what block of script is running just right now, runtime?

print a()             #takes couple of seconds, 3s
print b()             #takes couple of seconds, 3s
pass
print c()             #takes couple of seconds, 4s
print d(), \
      t,y,u,i,o       #takes couple of seconds, 4s
print z

So to know (report) what is running in the second 7th, for example.

report(7s): print c()

EDIT:

We keep the above as it is to justify the comments given ;) however below we describe our questions in more details.

A Python code is being executed line by line (or better block by block). See for example:

in code.py:

for i in xrange(10000000):                #assume this will take some seconds
   pass

print 'something'
#another time consuming job
for j in xrange(10000000):                #assume this will also take some seconds
   pass

print 'another thing'

We were thinking having a time thread which samples every 5 seconds to print (i.e., report) where we are in the code in runtime. So to have every 5 seconds printing what just happening during the execution.

Example output:

>>> 00:05 in progress: "for i in xrange(10000000):..."
>>> 00:10 in progress: "for i in xrange(10000000):..."
>>> 00:15 in progress: "for j in xrange(10000000):..."
...

This question seems really hard to understand to me. What is your expected output? What exactly do you mean by the "block of script"? — Andrew Gorcester, Sep 20 '13 at 07:28
Your question is surreal. "So to know (report) what is running in the second 7th, for example". Report what? Second 7th of what? That's no example — Vorsprung, Sep 20 '13 at 07:38
Maybe this is something you are looking for: http://stackoverflow.com/a/2569696 — oojeiph, Sep 20 '13 at 07:40
Are you saying that you need a duration that took to execute a line, let's say `print "hello"` ? — Joyfulgrind, Sep 20 '13 at 07:44
@Gcmalloc: Note that `xrange` example is just to **demonstrate a time consuming job**, nothing else. — Developer, Sep 20 '13 at 07:54

def fowia(signal, frame):
    print frame.f_lineno


import signal
signal.signal(signal.SIGHUP, fowia)

for i in xrange(10000000):                
    for k in xrange(100000000):
       pass

print 'something'
#another time consuming job
for j in xrange(10000000):                
        pass
print 'another thing'

To use this simple example, start it running then find the pid number of the process from another shell. Then send a HUP signal to the process. It will print the current line number. See http://docs.python.org/2/library/inspect.html for a list of other program source introspection methods that can be used

fowia = find out where I am, btw :)

I'm afraid `signal.SIGHUP` + others are not available in Windows! We updated tags. — Developer, Sep 24 '13 at 01:07
