newb: How to call one modue from other

[johnny]

I have a module called ftp and I have another module called
processKick. What I need is to have processKick, create fork and
execute ftp like below.

Relevant processKick code as follows:

def do_child_stuff():
ftp

def fork_test():
pid = os.fork()
if pid == 0:
# child
do_child_stuff()
os._exit(0)
# parent - wait for child to finish
os.waitpid(pid, os.P_WAIT)

Can someone also tell me what is the purpose of
if __name__ == "__main__":

Do I have to call, main of ftp module within processKick?

Thank you in advance

Here is my ftp module:

import ftplib, posixpath, threading
from TaskQueue import TaskQueue

def worker(tq):
while True:
host, e = tq.get()

c = ftplib.FTP(host)
c.connect()
try:
c.login()
p = posixpath.basename(e)
fp = open('H:/ftp_download/' + p, 'wb')
try: c.retrbinary('RETR %s' % e, fp.write)
finally: fp.close()
finally: c.close()

tq.task_done()

if __name__ == '__main__':
q = TaskQueue()
#host = 'ftp.microsoft.com'
host = 'mysite.com'
c = ftplib.FTP(host)
c.connect()
try:
#c.login()
c.login()

#folder = '/deskapps/kids/'
folder = ''
for n in c.nlst(folder):
if n.lower().endswith('.doc'):
q.put((host, n))


finally: c.close()

numworkers = 4
for i in range(numworkers):
t = threading.Thread(target=worker, args=(q,))
t.setDaemon(True)
t.start()

q.join()
print 'Done.'

Reading the Python Tutorial helps a lot.

Yes, because the original script author didn't want to call a
function inside that module, instead, he wanted to invoke the module
as a child program.

I did read "Dive Into Python", one week ago. It's a good book, but it
didn't cover this kind of situation.

Yes, it is good. It's also not the Python tutorial.

The Python tutorial is this document:

<URL:http://docs.python.org/tut/>

It's very beneficial to *work through* the tutorial, executing and
understanding each example before moving onto the next. (This is more
than "read the tutorial" that others sometimes suggest.)

didn't cover this kind of situation.

Chapter 2. "Your First Python Program"
The *very*first* example does this.

Now that you know more about Python, read it again, or the Tutorial,
and actually *do* the exercises...
