hi all,

I'm trying to understand regex for the first time, and it would be very 
helpful to get an example. I have an old(er) script with the following 
task - takes a string I copy-pasted and wich always has the same format:

 >>> print stuff
Yellow hat	2	Blue shirt	1
White socks	4	Green pants	1
Blue bag	4	Nice perfume	3
Wrist watch	7	Mobile phone	4
Wireless cord!	2	Building tools	3
One for the money	7	Two for the show	4

 >>> stuff
'Yellow hat\t2\tBlue shirt\t1\nWhite socks\t4\tGreen pants\t1\nBlue 
bag\t4\tNice perfume\t3\nWrist watch\t7\tMobile phone\t4\nWireless 
cord!\t2\tBuilding tools\t3\nOne for the money\t7\tTwo for the show\t4'

I want to put items from stuff into a dict like this:
 >>> print mydict
{'Wireless cord!': 2, 'Green pants': 1, 'Blue shirt': 1, 'White socks': 
4, 'Mobile phone': 4, 'Two for the show': 4, 'One for the money': 7, 
'Blue bag': 4, 'Wrist watch': 7, 'Nice perfume': 3, 'Yellow hat': 2, 
'Building tools': 3}

Here's how I did it:
 >>> def putindict(items):
... 	items = items.replace('\n', '\t')
... 	items = items.split('\t')
... 	d = {}
... 	for x in xrange( len(items) ):
... 		if not items[x].isdigit(): d[items[x]] = int(items[x+1])
... 	return d
 >>>
 >>> mydict = putindict(stuff)


I was wondering is there a better way to do it using re module?
perheps even avoiding this for loop?

thanks!
