Python syntax error ... not sure why

I've used a statement like the following before, however when I try using something similar it returns an error....

  File "test.py", line 73
    with open(hostsTxt, 'a+') as f1, open(hostsCSV,'a+') as f2, open(hostNameLook, 'a+') as f3, open(webHostsTxt,'a+') as f4:
            ^
SyntaxError: invalid syntax

Syntax with line above:

if hostName != "*" and hostIP != "*":
  with open(hostsTxt, 'a+') as f1, open(hostsCSV,'a+') as f2, open(hostNameLook, 'a+') as f3, open(webHostsTxt,'a+') as f4:

Any thoughts would be welcomed.

I tried both on Python 2.4 and 2.7 and it seems that same error happens on 2.4 and does not on 2.7

Python 2.4 - I did get the exact same error that you got.

Python 2.4.3 (#1, Nov  3 2010, 12:52:40) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> if hostName != "*" and hostIP != "*":
...   with open(hostsTxt, 'a+') as f1, open(hostsCSV,'a+') as f2, open(hostNameLook, 'a+') as f3, open(webHostsTxt,'a+') as f4:
  File "<stdin>", line 2
    with open(hostsTxt, 'a+') as f1, open(hostsCSV,'a+') as f2, open(hostNameLook, 'a+') as f3, open(webHostsTxt,'a+') as f4:
            ^
SyntaxError: invalid syntax

Python 2.7 

Launching python -O
Python 2.7.2 (default, Apr 17 2012, 22:01:25) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> hostIP ='localhost'
>>> hostName = 'abcd'
>>> if hostName != "*" and hostIP != "*":
...   with open(hostsTxt, 'a+') as f1, open(hostsCSV,'a+') as f2, open(hostNameLook, 'a+') as f3, open(webHostsTxt,'a+') as f4:
...     print 'testing'
... 
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
NameError: name 'hostsTxt' is not defined

As far as I know, you are trying to use with open with python 2.4 which is not supported.

Look at the lines before it, there will be a parenthesis or bracket missing.

That, or you have a python version that doesn't support with at all, the syntax wasn't introduced until python 2.6.
