Re: splitting a long string into a list

still having a heckuva time with this.

You don't seem to get it.

here's where it stand - the split function doesn't seem to work the way
i expect it to.


longkw1,type(longkw): Agricultural subsidies; Foreign
aid;Agriculture; Sustainable Agriculture - Support; Organic
Agriculture; Pesticides, US, Childhood Development, Birth Defects;
<type 'list'> 1

longkw.replace(',',';')

sample = "eat, drink; man, woman"
sample.replace(";", ",")
'eat, drink, man, woman'
sample
'eat, drink; man, woman'

Aha, Python doesn't replace in place, it creates a new string instead.

Agricultural subsidies; Foreign aid;Agriculture; Sustainable
Agriculture - Support; Organic Agriculture; Pesticides, US, Childhood
Development


kw = longkw.split("; ,") #kw is now a list of len 1

sample = "eat+-drink+man-woman"
sample.split("+-")
['eat', 'drink+man-woman']
sample.split("+")
['eat', '-drink', 'man-woman']

Aha, Python interprets the complete split() argument as the delimiter, not
each of its characters.

Do you think you can combine these two findings to make your code work? You
will have to replace() first and then split().
