py2exe - generated executable freezes when connecting to socket

Question

Pardon my ignorance as I'm still a beginner in coding.

I'm trying to convert a python script I wrote to a Windows executable program using py2exe. However, though I am able to successfully convert the script, the executable doesn't seem to be fully functional.

After much debugging, I have isolated the cause and the following code seems to be the problem

host = str(raw_input('Enter Host IP Address: ')) 
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect((host, 5000))

The problem does not occur when the script is executed from Pydev itself and the script is able to run without problems. The windows executable which is a console application just hangs when trying to connect to another host.

Is this a known issue or am I doing something wrong? Any help is much appreciated.

Hello!

Are you able to input the IP address? Reading that thread it seems that py2exe requires a special windows argument to launch a console. Otherwise, raw_input tries to read from the standard input, and hangs/crashes because it does not find anything.

Given the age of the thread, I checked py2exe doc: you might want to try to put your script in the console attribute.

I really think that the behavior is related to raw_input, and that it is not caused by the socket operation.
