Unable to lookup keys in dictionary

I actually figured out the solution to my problem, of all times, right
after I finished sending this mail. It seems P4Python returns a command
as a dictionary, also inside of an array. The solution is in the
following code:
 

	from P4 import P4, P4Exception
	p4 = P4()
	p4.port = "rsgnwep4s1:1666"
	p4.user = "mfielding"
	 
	try:
	   p4.connect()
	   info = p4.run("info")
	   info = info[0]
	   print info
	   s = info['serverVersion']
	   print s
	   p4.disconnect()
	except P4Exception:
	   for e in p4.errors:
	     print e

Subject: Unable to lookup keys in dictionary


I am trying to run p4python API on top of python 2.5.2 and am extracting
a dictionary from perforce. The following code returns the output that
follows it:
 

	from P4 import P4, P4Exception
	p4 = P4()
	p4.port = "erased"   #deleted
	p4.user = "erased"   #deleted
	 
	try:
	   p4.connect()
	   info = p4.run("info")
	   print info
	   p4.disconnect()
	except P4Exception:
	   for e in p4.errors:
	     print e
	 

Output:

	 
	[{'userName': 'mfielding', 'clientRoot': 'c:\\perforce',
'monitor': 'enabled', 
	'serverRoot': 'H:\\p4root\\', 'serverVersion':
'P4D/NTX64/2007.3/143793 (2008/01/
	21)', 'serverDate': '2008/08/12 11:18:56 -0400 Eastern Daylight
Time', 'clientAd
	dress': '10.24.20.97:1918', 'serverLicense': 'Mad Doc Software,
Inc. 140 users (
	support expired 2008/05/31) ', 'serverAddress':
'rsgnwep4s1.rockstar.t2.corp:166
	6', 'clientHost': 'nwew-mfielding', 'security': 'enabled',
'password': 'enabled'
	, 'clientName': 'mfielding'}]

I did this to test that I was receiving a dictionary back from the
server, which I clearly am. I then followed by adding the following
lines to the code:
 

	print info
	s = info[serverVersion]
	print s
	p4.disconnect()

I would expect this to print out P4D/NTX64/2007.3/143793 (2008/01/23),
but instead it spits out the following error:
 

	Traceback (most recent call last):
	  File "test.py", line 10, in <module>
	    s = info[serverVersion]
	NameError: name 'serverVersion' is not defined
	 

Changing "s = info[serverVersion]" to "s = info['serverVersion']" only
gives me another error, which is:
 

	Traceback (most recent call last):
	  File "test.py", line 10, in <module>
	    s = info['serverVersion']
	TypeError: list indices must be integers

 
If anyone has any idea what is going on here, I would appreciate the
help. I've spent a few hours over the past two days trying to figure
this little quirk out, but to no avail.
