Python Script Error in Windows 7

Question

I am trying to run this following script in here and getting this NameError. I have added path variable in Windows 7.

C:\Users\myname>python
Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:01:18) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

>>> script.py
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'script' is not defined

This is the script I am trying to run :

#!/usr/bin/python
import sys, string, time
from socket import *
host = "192.168.0.98"
port = 80
print "Open TCP connections to: %s, port %s" % (host, port)
while (1):
    s = socket(AF_INET,SOCK_STREAM)
    s.connect((host, port))
    s.send("abc")    
### test: donot close.  s.close()  
time.sleep(0.1)
print ".",

Thank you all.

You are trying to type filename in interactive python shell (after launching python). Try python script.py in Windows' cmd. — Łukasz Rogalski

You have a small typo in your code. You might remove the , at the end after the print statement. — albert

You need to do python script.py instead, from the command prompt not from the Python interpreter.

However, if you are in the Python interactive interpretor in the same directory as your script, as @Tuan333 points out, you can do:

>>> import script

or

>>> from script import something

to get access to functions and classes defined in the script (note that it is script in this case, not script.py because you are treating it as a module). However, as @ŁukaszRogalski points out, this is not equivalent to running the script from the command prompt as described above.

your solution would indeed be ideal. I just want to elaborate a bit more: if you have a script, you can also run it using interactive python interpreter by doing >>> import script

@Tuan333 import script, not script.py, and this approach is not equivalent to running python script.py (in general case).

@ŁukaszRogalski ah yes. there should not be .py in there. You are right, doesn't work in general, but in some simple case as this example, it should suffice.

You need to call the script all on one line

C:\Users\myname>python C:\path\to\script.py
