Hi,

Im just starting development in PyQT, and I have quite a basic thing i'm trying to do which I would find quite easy using something like PHP, but i'm struggling with python.

Not sure if im posting in correct place.. but

Basically I have a string like the following:

name:Example;
link:www.google.com;
datetime:20100209
|
name:Example2;
link:www.yahoo.co.uk;
datetime:20090808

So each result is seperated by a pipe (|) and key value pairs are seperated by a semi colon, then by a colon.

I want the ability to put these in to some kind of array so I can create a results page with lets say the following:

Result 1
Name: Example
Link: www.google.com
Datetime: 20100209

Result 2
Name: Example2
Link: www.yahoo.co.uk
Datetime: 20090808

Could someone help me with this snippet?

Thanks

Is split not doing the job for you?

Something like this...

Code:
for result in data.split("|"):
  for line in result.split("\n"):
    idx = line.find(":")
    key = line[:idx]
    value = line[idx + 1:]
    print "%s: %s" % (key, value)

I have tried split... but ive had a few issues with it, I eventually tried something like key,value=str.split(":") which was quite far down in about 3 for loops, and I was getting error messages, like there was too many loops for it to do that.

At present I have:

Code:
for eachResult in resultsArr :
	eachResultCount=eachResultCount+1
	lineArr=self.splitSearchResults(eachResult,';')
	# Loop through each of the lines in the result
	for eachLine in lineArr :
		eachLineCount=eachLineCount+1
		eachAttribute=self.splitSearchResults(eachLine,':')
		# Loops thruogh the key and values for this line
		for value in eachAttribute :
			eachAttributeCount=eachAttributeCount+1

This looks like it does the job perfectly... although I'm not exactly sure what its doing fully.

Hopefully this kinda thing will come more naturally as I get better, this is only my first attempt!

Thanks

You'll get the hang of iterating directly that way, and it will be refreshing.

It doesn't do the job perfectly... but its a lot closer to what I had before, it doesnt seem to be sp,litting on the ; but hopefully i'll be able to follow what youi've put to do that.

Maybe in the second line you could try replacing:
result.split("\n")
with:
result.split(";\n")
