replacing substrings within strings
Hi
I was wondering if there was a nicer way to swap the first 2
characters in a string with the 4th and 5th characters other than:
darr=list("010203040506")
aarr=darr[:2]
barr=darr[4:6]
darr[:2]=barr
darr[4:6]=aarr
result="".join(darr)
The above code works fine but I was wondering if anybody had another
way of doing this?

Thats the same code. I was wondering if the string manipulation can be
done without an excursion into the list world.

Re: replacing substrings within strings
Thanks all. I usually turn strings into arrays for processing. I was looking to see if that was the best way to do it from others that use python.

multi processes
Hi Heres a poser. I want to start a program 4 times at exactly the same time (emulating 4 separate users starting up the same program). I am using pexpect to run the program from 4 separate locations accross the network. How do I start the programs running at exactly the same time? I want to time how long it takes each program to complete and to show if any of the program initiations failed. I also want to check for race conditions. The program that I am running is immaterial for this question - it could be mysql running queries on the same database for example.

xml.sax parsing elements with the same name
I have an event log with 100s of thousands of entries with logs of the
form:
I am using xml.sax to parse the event log. The trouble with the file
above is when I parse for result value I get the last result value
(Blocked from above). I want to get the result value triggered (the
second in the event).
my code is as follows:
def startElement(self, name, attrs):
if name == 'event':
self.eventTime = attrs.get('eventTimestamp',"")
self.eventUniqueId = attrs.get('uniqueId', "")
if name == 'result':
self.resultValue = attrs.get('value',"")
return
def endElement(self, name):
if name=="event":
result= eval(self.filter)
if result:
...
How do I get the result value I require when events have the same
names like above?

how do I keep track? The first result value is outside a filters
section and the rest are. Do you mean something like:
def startElement(self, name, attrs):
if name == 'event':
self.eventTime = attrs.get('eventTimestamp',"")
self.eventUniqueId = attrs.get('uniqueId', "")
if name == 'result':
self.resultValue = attrs.get('value',"")
if name == filters:
if name == 'result':
self.resultValueF = attrs.get('value',"")
return

Actually that is the exact code run from a python shell. Try it
