how to continue execution after sys.exit() command

Here i'm reading and comparing values from the two logs using 'for' loop.Problem is i'm not able to continue to next TC after sys.exit command. Let me know if required more clarification

f = open('/tmp/ftplog', 'r')
    for line in f:
        m = re.findall("5\d+", line)
        #print m
        fd = open('/tmp/tellog', 'r')
        for line in fd:
            n = re.findall(r"5\d+", line)
            #print n
            if  m == n:                 
             print "passed"

            sys.exit()  

####TC-02####

def tc02(ipadrr,login,password,ftpipaddr,ftplogin,ftppassword,ftpfilename):

    try:    

                telconn2 = pexpect.spawn(ipadrr)

Answer 1

You can add hooks that will be executed on exit using atexit. http://docs.python.org/2/library/atexit.html?highlight=atexit#atexit

However, needing to do this in a simple script is usually a sign your logic is wrong. Do you really need to exit? Could you throw an exception instead? break? return? For example, try having the logic in a function, the function returning when it is done, and some code that calls it and does something with the returned result.

Answer 2

sys.exit actually throws a SystemExit exception, which you can catch, but you really shouldn't. Restructure your program so you don't have to.

Answer 3

try this

print "passed"

return ####instead of sys.exit use return

Answer 4

A way to do this if it's really needed is to call the same script but with different parameters in a subprocess just before you exit it like this:

import subprocess
p = subprocess.Popen("exec your_script.py -parameters parameter", stdout=subprocess.PIPE, shell=True)

Then you can add some checks for a specific parameter that you will provide and execute only this part of your code (e.g. the tc02() function that you need).

Just keep in mind that once you call the script as a subprocess, you won't be able to stop it from the console with Ctr+C, since this will kill the parent process, but not the child processes. In order to kill everything you need to call a method like this:

p.kill()
