Hi everyone,

I was developing a little program that uses regular expression, initially I set up

an expression which looks like this :

buf = re.compile("[a-zA-Z]+\s+")  

this was to match the followint string:

str = 'Data sparseness is an inherent problem in statistical methods for natural language processing.'

Result:

['Data', 'sparseness', 'is', 'an', 'inherent', 'problem', 'in', 'statistical', '
methods', 'for', 'natural', 'language']

the result is that, it gets all the tokens except the last one with the processing+ dot (full stop at the back)

can anyone suggest how I can achieve to handle all the cases with the above

RE.

Reposted for some correction

thanks in advance
